What do you do when a giant encroaches on your territory?

18 Sep

This week, Box held its annual conference, BoxWorks 13.  The online storage leader made two big announcements about products it intends to launch in 2014.

Box Notes are editable web pages, which users can write, edit, comment on, and embed content within.  Sound familiar?

Box also announced that it will be adding metadata to files, so that users can attach structured data to those files.  Again, sound familiar?

Both of these 2014 initiatives are available to PBworks users today.  In fact, they’re even part of our free business product.

This isn’t the first time we’ve seen giants encroach on our territory.  Back in 2008, Google unveiled Google Sites, their free wiki product, aimed squarely at the wiki hosting market, and companies like PBwiki (which was our old corporate name).

So what do you do if you’re a startup that’s facing a challenge from a giant company that has millions or even billions of dollars to spend?

The answer is to play to your strengths, and keep innovating.

In 2008, we shifted from simple hosted wikis to a broader collaboration suite.  Today, we have the broadest suite on the market, with project management, file sharing, management reporting, and social, in addition to wiki-style collaboration.  As a result, we can deliver an integrated solution that our key customers use to make thousands or tens of thousands of employees worldwide more productive.

Meanwhile, we host more wikis than ever.  The attention Google brought to the market helped generate more interest than before.

We introduced file and page properties (asset-level metadata) earlier this year.  Since then, we’ve released our reporting tools, as well as a visual approach to managing workspaces.

By the time 2014 rolls around, we’ll have released several more key features that are pushing the boundaries of the collaboration space.

Giants are powerful, but their size slows them down.  When they encroach, use your nimbleness to keep innovating.

Last Chance For Free Passes To Enterprise 2.0

30 Mar

Each year, we attend the Enterprise 2.0 conference.  Attending helps give us new ideas for the product, as well as helping spread the word about PBworks.

This year, the conference has a special promotion–if we get 80 people to sign up for a free EXPO pass to the show (June 20-23 in Boston), they’ll give us a free full pass.

If you’re thinking about attending the show or will be in Boston at the time of the show, you can sign up for a free pass and do us a favor at the same time.  Tell any friends who might be interested as well!


A number of folks have commented that the pass price comes up as $50.  This is true, but if you submit, on the very next screen, the $50 is removed from the price, leaving it free.  You will never have to enter a credit card or pay anything.

Introducing the PBworks Template Store

12 Jan

The Template Store serves many professions
(Image appears courtesy of Joe “Shiggy” Sciglitano)

The great thing about PBworks is that you can use it to do just about anything.

The bad thing about PBworks (at least for those of us who tell its story for a living) is that you can use it to do just about anything.

Saying that PBworks combines wikis, document management, project management, social networking, microblogging, and real-time communications (with integrated voice coming soon) requires strong lungs.  More importantly, simply listing all the features in PBworks doesn’t necessarily tell you how it solves *your* particular problem.

That’s why we built the Template Store.

Not only does the Template Store show how you can use PBworks workspaces to solve specific problems, you can clone these examples into your own PBworks network, where you can customize them to meet your needs, or even convert them into custom workspace templates.

Plus, all 25+ of our templates are free of charge to PBworks users.

There are templates for specific industries (e.g. a Client Engagement Template for consultants, a PR Client Extranet for marketers) as well as specific functions and processes (a Branch Office Intranet for corporate use, a Presales Extranet for sales, and a Competitive Analysis Template for marketing).

If you’re already using PBworks Business Edition (formerly Project Edition) or Legal Edition, you can access the Template Store from your network — chose ‘Workspaces’ and select “Template Store.”

If you don’t currently have a network, you can preview the Template Store here.  You can even submit your own templates for inclusion.

Check out the Template Store and see if there’s a template to solve your problem.  And if not, leave a comment, and we’ll work on building one!

A/B Testing at PBworks

16 Sep

At PBworks, we take our data seriously.  So it should be no surprise to learn that we use A/B testing techniques to aid our product and website development decisions.  Having a web-based product means that we can quickly learn what our customers like and what they don’t like and make changes accordingly.  If you’re not familiar with A/B testing, Avinash Kaushik has a great primer.

Analyzing Test Results
As the data analyst here, an A/B test for me can be reduced to just a few simple numbers.  Those would be: (1) the difference in conversion rate from the control group and (2) the level of confidence we have in that difference.  The first number is easy to calculate and explain to the rest of the team, e.g. “The test site resulted in 30% more sign ups that the current site.”  Everyone gets that: engineers, marketers, and managers.  As an example, here is how one of our recent website experiments played out over a 2 week period:


In the chart, each day shows the cumulative conversion rate (i.e. total sign ups since the beginning of the test divided by the total visitors since the beginning) for the test site (Test) and the current site (Control).  Notice how well the test site is outperforming the current site.

However, anyone who’s played games of chance can tell you numbers that look good on this turn, may not be so hot on the next.  For example, if you flip a quarter 5 times and it came up heads 4 times, would you feel confident on betting that the coin is biased towards heads?   What if you flipped 80 heads out of 100 tosses?  At this point, you’d be much more confident that the coin is biases towards heads.  In our A/B test, we measure the conversion rate for a small subset of all visitors, let’s say 10,000 visitors with 100 sign ups.  Do we believe that the this conversion rate will be the same for the millions of visitors we expect in the months to come?  Do we need to test 1,000,000 visitors to be confident that the observed increase will apply to all visitors and was not just the luck of the draw?

Statistical Confidence
Statistician have figured out a way to calculate a numerical representation for the confidence that the population (i.e. the millions of visitors our site will see in the future) will show an increased conversion if the sample (i.e. the thousands of visitors that have hit the test site so far) shows an increase.  Though we have this reliable, albeit complex, formula for the confidence number (using a 2-proportion z-test, or an online calculator), explaining what this number means to the rest of my team hasn’t always been easy.  How would you interpret: “We saw a 30% increase in sign ups and we’re only 90% confident there is an increase.”  What this means is that if we ran this test 100 times, we’d expect in 90 cases to see an increase (though not necessarily a 30% increase) and in the other 10 cases to see a decrease or no change.  For some organizations, this would be enough confidence to make the test site the actual site for everyone, for others, it wouldn’t.  The decision of what confidence level to use comes down to a trade off of speed and certainty.

Unlike coin flipping, though, recreating the experiment over and over again would take too long and negate most of the gains we expect from A/B testing.  So it is difficult for some to internalize what this confidence level represents.  Many people, especially those that are risk-averse, don’t like dealing with probabilities and will keep asking for more data.  But you’ll never be 100% certain that the test site is better converting than the current site.  So at some point you need to stop collecting data and make a decision.

Sunrise Charts
What I’ve found to be a useful aid in getting many of the risk-averse types to accept some risk has been to overlay confidence areas in the time series chart like so:


My team has dubbed this a “Sunrise Chart” (yeah, I’ve never seen a green sky during a sunrise either, but you get the picture).  The solid black line and dashed blue line are the same as in the previous chart and the colored bands represent confidence levels.  If the test line veers into the green area we have a 90% level of confidence that the test site out-converts the current site.

Many of the less technically-inclined members of my team find that this chart makes sense on a more intuitive level than a statement like: “We saw a 30% increase in sign ups and we’re 90% confident there is an increase.”  The chart shows this same information, but it also shows two other things.  First, the random day-to-day fluctuations in conversion rate average out and the rates stabilize over time.  When people see more stable conversion rates, they are more inclined to feel confident in the difference they see.  Second, this chart shows that as we collect more data over time, a smaller and smaller increase is needed to reach a specific confidence level.  This is essentially the same piece of information as seeing the conversion rates stabilize, but since these confidence bands are generated from a complex mathematical formula, it gives some peace of mind that the underlying math is jibes with their gut.

To wrap things up, at PBworks we believe that A/B testing is an important tool to develop the most relevant software for our customers.  However, when experimenting, it is not enough to simply compare the conversion rates of the test site with the current site.  We want some level of certainty that if we do see an increase, it is not simply due to a lucky draw.   That is where confidence levels come into play.  Finally, and perhaps most importantly, it’s not enough for just the technically inclined to “get it” with a statistical analysis of the results.  Rather the whole team needs to be on board with the decisions that result from the experiment, so everyone needs to be comfortable with the analysis.  This is when Sunrise Charts can be a valuable aid.

Get unlimited wikis and users for your school district with District EditionN

4 Aug

In the beginning, individual teachers bought our Classroom Edition.  Then as word spread, entire schools bought our Campus Edition.  Now, just in time for the 2009-2010 school year, we’ve taken the next logical step and launched our District Edition.

PBworks District Edition gives each K-12 school district that signs up an *unlimited* number of wiki workspaces and users.  Now you can share PBworks with every single student, teacher, administrator, parent, and yes, janitor in your school district.

Already, districts like Baltimore County Public Schools and the Wake County Public School System have signed up…maybe you can convince your district to be next!  Here is our announcement.

Each time, we’ve been surprised by the enthusiasm for our larger Academic packages, but we think District Edition is probably the upper limit for size.  Unless….

Country Edition anyone?

PBwiki is now PBworks

27 Apr

The beginning

Back in early 2005, I was helping a number of folks out by setting up private wiki installations on my servers. I got tired of setting each wiki up by hand and had a vision for a simple wiki service that people could set up themselves. In fact, I’d make it as easy to make a wiki as making a peanut butter sandwich. So at 1:00 AM on May 29, 2005, I registered By 8am, I had my first users testing the service, and within 48 hours over 1,000 groups were trying the service out.

Since then, the company has grown from just me to a staff of 29. We received venture capital financing, hired a professional CEO, and totally rewrote and improved the service and interface to be a powerful but approachable collaboration tool for individuals, groups, non-profits, educators, and corporations all around the world. Now we have some 3,000,000 users a month on well over 800,000 workspaces.

Why we’re changing our name

The product has evolved well beyond the definition of a ‘wiki’. What we have now is not just some user-friendly generic wiki; it’s an increasingly full-featured hosted collaboration environment, used by tens of thousands of companies around the world to get their work done. It became clear that ‘wiki’ was caging us in.

We went through a lot of different possible names, some of them dramatically different (Viscade) and some of them adorable but too long (Accordiance) and ones evocative of the wild west (Collabero). But we kept on coming back to the warm fuzzies that PBwiki seemed to give folks and the enthusiastic community built around PBwiki. While we knew we needed to drop ‘wiki’, we ultimately couldn’t find it in ourselves to get rid of the ‘PB’.

Introducing PBworks

After months of deliberation and consideration, we’re proud to introduce PBworks. All of your existing wikis have been magically ported over to thanks to the diligent work of our engineering team. Some things will change, like your URL, but the service still works and costs just the same. You can check out our FAQ on the renaming for more details about how your PBwiki will change.

Thanks for your support

We’re glad to have you with us as we go through this development. As I’ve remarked to many friends, it’s been a joy to watch my company grow and mature from a project I put together in a weekend into a real professional enterprise Software-as-a-Service offering, one akin to watching a child grow up, take its first steps, make its first friends, and go to school.


For those of you curious what that first version of PBwiki looked like, here’s the first version’s front page, thanks to the magic of The Internet Archive.

Much Love & Collaboration,
