I think Asher signed up quite a few after the total CL list he came up with, I think it was only last week still. He published two last week, so that's confusing me at the moment. :)
What he probably needs to do is run a list of the top 50 who have commented with unique users over a week's period of time. That would probably draw more of those folks out. Not sure if that query is possible, since he was having us do that individually last week, too. :)
