I call it CB radio. Here's why
1. Everyone has a handle
2. There is no continuous thread of one person talking-translation-someone walks all over you
3. Every word is searchable, meaning it has many "channels"
4. Some people are anchors just like channel hogs in the CB era
5. Some people are on it night and day, just like CB radio
6. Some user find ways to "sell" via their Tweets, so did many
8. Conversations can go on for days, with no end
