How Much Should You Tweet Per Day?

The key with all of these things, tweeting, replying, consuming and direct messaging is it's about providing value. I think if you're doing and we'll talk about how much time this can take or not in another one of your questions. It may sound like a lot, but I actually don't think it's necessarily that much of a time commitment. So I'm curious your reaction to all of that? Does that make sense? Any questions come up for you?
