You can try
this site which is headed in the direction you are looking for, and the most recent replacement to what pokerpulse was offering.
Just be careful about which links you click on!
By the way, the most interesting thing about this site, is that it cuts thru the BS player numbers posted by the poker sites, and make it absolutely clear to anyone who already doesn't understand those numbers, that the majority of the Poker sites reported numbers are players playing freerolls, play money and uber-low buyin tournaments.
