if you found a website directly relevant to your industry/service and they have more than 1,000 pages that allow unmoderated html comments with instant submission and dofollow, how many links would you throw down? most inner pages are pr0 however main page is a 3 and i have found several pages with pr2 and pr1 and all pages are directly relevant, meaning if i go to any inner page i will find my competition thanks to adsense.
