Reader "Twitter" asks in a comment thread:

Orin, Are you twittering yet? What's ur twitter-name?

A few days ago, I created a Twitter account and posted my first tweet. It was indeed profound: "Testing twitter to see if this is worth doing."

  I really don't get what I'm supposed to do with Twitter, at least given that I already seem to blog all day. Twitter just seems like a blog where you can't write anything in detail, and I don't see what that adds to the VC. So I'm not sure I'll do a lot or even anything with it. But hey, if you're one of these Twitter people, and you want to follow me, feel free to follow me at "orinkerr".
