It's not their fault, however, it's mine. Sorta. See, Basecamp is a pretty swank application for project management: fast, easy, light. I was up and running in no time. I invited people and made groups. Piece of cake. I even belong to other Basecamp groups, however, I'm so reliant on e-mail and RSS that stuff has to come to me. I never realized that activity can happen in Basecamp that requires me to log in. That's another story altogether.
What I noticed (and perhaps this is a problem with social aps), is my motivation level is affected by the motivation level of the community, whether it's the community at large, or my own private one. As usage by the group has slipped off, so has mine. And I'm too lazy to cancel because you just never know. This might come in handy.
There's something to study here in this behavior. Is this a flaw with social networks? For example, do some social networks work in certain cases (LinkedIn for example, is something I use *after* I meet someone, never to meet someone for business. Maybe that's the point, I don't know).
Perhaps I can solve this by getting a rapid project manager to run the Basecamp activities for our group? Of course, this gets into issues of control or no control (think the wiki model)... should it be open to the world at large or does someone need to be in charge and control?
