While building backlinks everyone becomes obsessed whether the backlink is do follow (not nofollow) and what Pr is that page where the backlink is on. From my experience and what I actually got, I got PR 4 for a domain that has all it's backlinks from PR 0 / Pr 1 websites. More over, On another domain and while commenting on blogs to get backlinks. Google webmaster tools shows a backlink from a .edu wordpress post that has nofollow tag and this means google indexed the nofollow tag and indexed the freakin link. My website is on the first page (2nd position) on google for a popular term (health related) and is still doing good. So to all those who spend half of their day posting about the nofollow myth, Just invest that time in backlinking where it is pr 0 or pr 7, whether it is nofollow or not. In the end it is just a backlink. Just get it from a good neighborhood and you will do just great. I can't seem to be able to prove my claims without actually revealing my domain but that is not gonna happen so please just believe what I have just wrote. Cheers.
