Now I don't mean to complain, but I was curious if perhaps the feature was not working.
According to the tag badge page golden tag badges are awarded for 1000 upvotes in a given tag (not counting wikis).
According to the [starcraft-2] tag. I've hit that number (actually I hit it over a week ago).
Now at first I thought, perhaps that number does not represent the correct number of upvotes, but I've been lead to believe otherwise
The number next to the user names reflects the number of non-community wiki answer upvotes for each user. This is the same algorithm used to award the tag-based badges, so if you ever wondered how close you are to getting one of those badges, now you know!
