Possibly going through the list of profiles with the most trust, recognition, and the other statistics on the Vod's BPIP could be a good idea if users here are too humble to request their profiles to be converted into a infographic
Not sure how you're going to wade through thousands of posts per user to find substantial quotes by them though. That would be an achievement in its own right. Take these for example:
Username Posts
philipma1957 30766
Amph 28909
BADecker 26676
Lauda 25251
deisik 22011
Phinnaeus Gage 21967
ChartBuddy 21804
Gleb Gamow 20486
hilariousandco 20398
For such a small amount of users that's a lot of posts to wade through.
