Dang, another one! Gather.com? How many social networks does one need to belong to to be known as "social?" One? Two? Three? I think 2 is sufficient: (1) professional and (2) personal. That's why I belong to LinkedIn and Facebook. And of course, every Web 2.0 out there is trying to get you to join their "community" while you post & enjoy videos.
I like being social... we humans are social by nature. But I still need my Jim-time, which social networks don't provide.
