Information Overload
The scary part of this craigslist post is that he's only mostly kidding. I thought I was insane to mess with maybe eight or nine of these "social software" sites, and he's gone and mentioned another half-dozen I've not even heard of. I think the FOAF concept makes the most sense, but sadly it's the hardest way to play.
Ah well. Now that I'm paddling around in Google's Orkut experiment, I'm full up for now. (Though e-mail me if you haven't yet been deluged with Orkut invites. It can't be that exclusive if I got in!)
