PBWiki is on a bit of a roll. After confirming a $2 million round of financing last week, they’ve just launched a partnership with 30Boxes that allows users to insert a calendar into a wiki. Actually getting the calendar into the wiki requires way too many steps, and I agree with 30Boxes founder Narendra Rocherolle that this should be made into a template option, as Jotspot did in 2006, shortly before their acquisition by Google.
Wikis are basically commodities at this point. There are dozens of hosted and unhosted versions to choose from, and revenue models are pretty thin. PBWiki has a loyal following of users, though, and has spent very little money getting to where they are today. We’ll see how they do over the next year.
