Jay - Im testing it now to see if in addition to the blog category, I want to add the blogs into the niche categories as well - I saw PBot was doing that and dont know how his results are for the niche cats, but will let you know when I finish my testing
sexobolic - some of those sites wouldnt meet my rules - like the pic sizes being less than 500 on the long side, same template over used already, sponsor content, etc - you can start submitting, but the reviewers would have declined some of those
