Social Bookmarking Stats

Social Bookmarking Stats is what I searched for month. Nothing special into that: social bookmarking statistics for my site. Just imagine how that would be nice if any webmaster could have stats for every page - social bookmarks made by other ppl. For now I found three social bookmark stats services:

http://www.backtags.com/

http://www.popuri.us/

http://www.socialmeter.com/

Sooth to say, no one works correctly.
