Could there be some gold in that pile of poo? I'm not too hopeful.
I also spent some time checking the top few users and found nothing of interest. I figured maybe they were the spammers who had managed to squeeze through all your filters, so I jumped to the bottom and checked out the last few users with the lowest post counts. Results were similarly discouraging. I couldn't find anything worth meriting in about 20 minutes of looking, so I just merited you instead for the effort. I'll take a longer look another time, but I'm not hopeful.
This seems to be another data point (along with Loyce's Report to Merit Sources thread) to disprove the oft repeated claim that there are a plethora of great posts and great users who are going under merited.
