Jimmie,
Yes, I think I'm getting the hang of it. You can follow people (and depending on their settings they may have to accept your request for this to happen), you can deny people/organization's requests to follow you, and you can definitely block people. I think there are some other features, but I haven't messed with them. I've actually had my twitter account for over a year. I had followed our local soccer team (Houston Dynamo) but upon logging in yesterday and seeing the flood of tweets they send every day, I decided to unfollow them. There isn't a tiered system (that controls the volume of messages that one receives) that I'm unaware about, is there? Like Ultra-fan, fan, casual? Where 'ultra-fan' receives tweets about what the players are having for breakfast any particular morning and 'casual' receives game scores? That would be nice.
