Hey thats really cool, fair play for putting the time and effort into it. I understand where people are coming from regarding the length issues with longer posts not always equalling quality posts, but I guess you have to draw a line in the sand somewhere.

Personally I think factoring in the number of 1st posts in large (20+ pages) would be a good indicator, if you could parse the thread titles for ANN, BOUNTY etc that would suggest that they're adding value by managing campaigns and thus have a lot of cred behind them.
