People who tweet what they eat. I don't mind the occasional 'those berries were nice' but some people go over the top. The exception to this rule is if they post a picture (twitpic) with it. You could analyze "eat", "lunch", "dinner" keywords. People who RT everything someone says. For example I follow several web designers and programmers as well as Nettuts. Nettuts just RTs everything the other people tweet. Very annoying. As other people have mentioned #moonfruit and #squarespace. Very annoying when they do it every single day. (Mayby analyse frequent hashtags in a certain period of time?)
