Thanks guys, now only i know that visitors don't make up the PR (hmmm...this means that my competitor might not have such high visitors as they claimed lol ) Btw, i found a blog which posted a 1050 quality do follow site which we can build backlink from but of course we have to post some quality comment if not it woun't get approved by the author.

PR or content? That is the great debate that needs to be answered. I think one should focus on content first. PR will come naturally.
