Thanks, Jason. It doesn't feel like a winner-take-all market to me and I think that's good for all of us, no? Facebook is good for keeping up with friends and family but I get the feeling that it degraded a little when they decided they also wanted to be Twitter.
Our simple idea is that you can't always indulge your interests with your friends and family because they don't share them. And sometimes you want to go deeper in a topic than you can on Facebook. No reason the two sites can't coexist, seems to me.
