Love the badge title/art idea. I'm not sure if we should reward people for being under a certain post count, since we don't have one for being over a certain post count, other than the user title, and that's not a badge anyway. Hopefully I'm not forgetting anything, though.
I think we should shoot for rewarding quality, anyway.
That being said, the name and badge art idea is awesome, and I wouldn't mind seeing it used in some fashion.
