When you view your tags on your user page, each tag has a number to the left - that's the total number of votes for all the answers you've given in that tag. To the right is another number - that's the total number of questions and answers you've submitted for that tag. Why the inconsistency?
I suspect that the vote count is there primarily because of tag badges, and if I'm right, it makes it even weirder. A tag badge requires a certain number of votes (100, 400, or 1000) on a certain amount of answers (20, 80, 200). So why show the vote count only for answers, and the tag count for both questions and answers?
