When I'm curious about which tags might be about to earn me another badge, it would be useful for the user profile to show the current "badge level" for the tags.
If I look at the bottom of the user profile where it's got tags and badges listed, the system clearly has all the information available - and I could just look through each tag and see whether I'd already got a badge for it or not. It would be simpler if the tags just showed the gold or silver badge icon "inline" though in the list of tags, just to the left of the tag name.
