I don't agree. Number of profile views might be result of several factors: controversial posts, temporary hype, daily visits of friends, vivid social relationships (without many quality posts), old members (less active now), link to profile page in signature etc.
I agree that post count ranking is not perfect either. Due to posts including only "lol", smiley, "good riddle", guessing in easier games, participation in story-telling games etc.
Good way would be to implement "thumbs up"/"thumbs down" for each post. So that members could rate replies of other members - if they were helpful, insightful etc. And take those points into account when rating members.
The new version of IP.Board will come out shortly. Let's wait for the improvements and maybe look for a modification then. Nonetheless, good idea.
