COMMUNITY 2.0 - Update

Since doing things together is the most important denominator of Web 2.0, you'll find many more symptoms of community forming in other categories. But COMMUNITY 2.0 is still a HUGE category. The funny thing with communities is that only few people really know what makes them tick. Finding a theme that makes people unite around a common interest isn't that difficult, but keeping them there - happy and active - and finding a sustainable reason to ask some money for being part of them (or to find other revenue streams) in most cases is still a challenge.
