I know what you mean. On the other hand, I think tweets are so short and the number of potential categories so large that this is a harder problem than it seems.
However, I think there’s more than just a technical problem here. Most people won’t enjoy being bothered to enter metadata with their tweets, and anything that raises the tweeting barrier (like having to stop to categorize a tweet before sending it) is probably not something Twitter will be interested in implementing.

Categories can be opt-in.
