As a general matter, the people I follow mostly just tell me when they have posted something on the Internet. Kind of the reverse of this post. That's fine, but isn't that just an RSS feed? If that is all you use Twitter for isn't Google Reader a more effective, efficient way to do this?
So, while I do enjoy my own tweets, they are utterly pointless, which may not be any worse than most tweets I see. You can follow me @DavidAnvil.
