Lots of good questions and responses. Just my 2 cents. if you want quality backlinks and want them for free, do it this way: Just go to Google and type in these magic words "Free pr9 backlinks" or "free (you fill in pr here) backlink". You will be amazed as to what is free out there. Set aside a couple of hours, a garbage email account, and voila...potentially dozens of high PR backlinks!
