We are very pleased to see Wikidot wikis used in many different scenarios and cases. And creativity of our users still surprise us.
The thing however that really is pleasing is the usage of private wikis — did you know that over 40% of all our wikis are private? And that about 30% of the users' activity is happening in non-public areas? Unfortunately we cannot have a "featured private wiki" (simply because they are not public) but certainly some of them would deserve attention.
So, what do people use private wikis for? Some of them are personal workspaces created to "keep things in one place", but most of them have been created for small workgroups, also business users, to help communication and organizing workspace and workflow. Just to mention a few areas of usage: software development, b2c communication, knowledge bases, project management etc. And it looks like Wikidot fits (almost) perfectly for the job. Although Wikidot wikis are free, many people use it for mission-critical tasks. Thanks for trusting us!
Also a very large userbase in the private realm comes from universities where wikis are used to support classes, student project and scientific work.
Private wikis (and the whole Wikidot too) is getting more and more popular and recently we have been getting a lot of requests for raising the limits of users in private wikis (each private wiki was limited to 50 users only). We usually do it without problems, but the amount of requests made the waiting queue a bit long. Today we have decided to remove the limit for all the wikis!
Good luck and have a nice wiki,
The Wikidot Team
BTW: Needless to mention, private wikis at Wikidot are still free!
