Now that's an interesting mod there. This would probably be the most 'fair' signature mod I have seen on forums. I think other forums should also include this to promote more discussions and not allow members to get away with 'thanks for sharing', 'i like this' kind of threads.
Probably you can also do the same for post counts, show two post counts, 1 with lengthy posts and another with actual number of posts. We would find out how articulate the member has been on forum
