"Karl Rove (KarlRove) is now following your tweets on Twitter."

Would that enthuse you? If so, you're a nitwit — a twitwit. "Karl Rove is following 96071 people." 116120 people are following him. Be impressed if you're one of the elite 20049 who follow him without being followed. If you want to be impressed with yourself. It's not recommended. Not in the twitterverse anyway.
