qole has the right idea here. Using either the posts:thanks ratio, or m.o karma will lead to more useful posts, and less "I agree" posts, because the rating will mean something. If we have a rank, people will think it means something regardless of whether it does or not, so why not actually have it mean something?

As for the "over 1,000 posts means something" issue... I'd just like to point out that munky261 is on that list, and... well... this post by bongo pretty much sums up why that means nothing (in context) (No offense meant, munky!) Posts do not equate to experience. "Thanks" and karma equate to experience. Can we come up with some equation that factors in: (posts optional, because... as I said, they're useless on their own, but useful compared to other items), thanks given, thanks received, m.o karma? It seems that some kind of rating that factors in all this information would be the ideal solution, and create meaningful ranks, which, IMO, should be the goal here.
