When you vote a question or an answer, the votes contribute towards the tag score.
It would seem to be that if an answer is marked as the answer, that says more about the the poster's strength in the area than an answer not marked as the answer. While this is accounted for in rep(via an additional +2 rep), why is it not accounted for in the tags? (Something like a +1 for the tags that the question has in addition to the amount of upvotes the answer has)?
I think that it is important to count how many times a user's answer has been accepted in a tag category, in addition to how many upvotes they got. Seems like a good idea to treat the answer checkmark as an increment to score in this regard.
