Findind **************** blogs with CommentLuv...does this work?

I find that a lot of the blogs are still no follow, so it really does no good for G. However, Yahoo and Bing do not use the no follow attribute so you are still building back links for ranking in those engines.

ah, that explains the higher number of backlinks in Yahoo vs Google.

Any suggestion though how to really find **************** links that works better than Glock, Market S and CommentLuv ??

I use URL Scraper urlscraper.com
It costs $10 so its not like your taking a big risk.
It has a setting where if you check it off it puts links into their own output file - (ie. the page doesn't have nofollow in the html code) It also sorts by page rank, etc. Anyway it speeds things up for me.

Note that you have to be semi-good at putting together good google queries for it to work well. If you just do a query on a keyword like "car" you'll get bad results. If you have a brain though and use something creative like
keyword "powered by Movable Type"
or
angelae8654
then you'll get better results.

Hope that helps.
