Post comments on 500 gay blogs (no sex)

Hi, I need someone to find 500 gay related blogs in english language, preferably linked to travel or linked to asia. No sex blogs! These blogs must be active (at least 30 posts and the last one not older than 1 month). The first part of your work will be to make a list of them that I will review to be sure they respect the criterions. The second part will be for you to post a comment on the last post of each blog with a link to my website. Not a post like "good idea" or "that's great", something more clever, in accordance with the last post (so you have to read it). I really insist on that. It also means that all your comments will be different. They should also include a few keywords that I will provide (geographical comments). One last thing: the links you will post MUST be real links: not just my webaddress written (html or other proprietary code compatible blogs only).
