I found the analogy I'm going to use from now on.
Twitter is the public square, where everyone can get a soapbox and yell at the crowds who are just milling around aimlessly.
CoSo is the neighborhood bar, where, whether you enjoying a Bud, a bud, or milk, you're welcome and the crowd is friendly. A 100 conversations going on around the room. Lots of laughing, a few very serious discussions, these are your people. And a whole bunch of us are pointing and laughing at all the birds.
