You have gained X reputation from upvoted answers. You have lost Y reputation from downvoted answers. You have gained Z reputation from accepted answers.
Even better might be to see which tags have generated reputation for yourself (or even other users). This would be a great way to be able to quickly tell how much authority on a given subject someone has. For example, if someone is answering my jQuery question, and they have > 10k rep, but < 100 of it is from answering/asking questions tagged with jQuery, that would be useful info.
