Thanks for getting to the bots (and thanks to Fred), which has made Saidit useful again. I've seen this in the mod logs.

Perhaps there is a way of counting users with comment karma above - say - 100, as this would likely help with a census. Reddit had a survey/census in its first 2 or 3 years, which is how everyone knew that the demographics were essentially early-20-something IT people. That was before the Digg infestation of 13-year-olds.
