It would be very interesting to be able to earn a few badges more than once.
I would like to see a system for these badges where you can earn them as many times as you want, but each time it gets harder and harder.
Commentator : Leave 10 comments on posts.
Commentator x2: Leave 100 comments on posts.
Commentator x3: Leave 1000 comments on posts.
Strunk and White : Edit 100 posts.
Strunk and White x2: Edit 1000 posts.
This could be implemented for many of the badges.
