The Washington Post has a system of badges for commenters.

You can nominate yourself or someone else for high-quality comments in the following categories, and if WaPo agrees, your comments will appear with one of these icons next to your name:

A badge for comments on politics and national affairs.
A badge for comments on Washington area news and trends.
A badge for comments on Washington area sports events and news.
A badge for comments on international affairs.
A badge for those trained by the National Weather Service as Skywarn Spotters.

If I could do a system of badges for the blog commenting here at Althouse, I might like having 5 different badges, but I'd have different categories! Help me fantasize about what the badges could be. And feel free to provide graphic design for the badges.
