Fifty characters
Chat, like life, is too short
Why post like haiku?

The problem is that too many characters is going to have TONS of scrolling going on. At 50, when I go into chat, I'm only seeing four posts. At more than a hundred or so, it's going to be impossible to use. But that's for better minds to figure out. Me, I want an indicator so we know when someone has actually posted something and a way to tag a user so, if you're replying to them, there's a quick way of referencing their ID. All told, though, this is a good first effort for a beta.
