Most people have no idea what a PR is to begin with? Probably one of the biggest arguments in the SEO world is just how important PR is to a website. While I would rather have a high PR, I would not base my judgement of a site's worthiness solely on PR. PR seems to be so unimportant that there are many times I will find a high PR site on the bottom of the SERPS. I think developing a campaign with nothing but PR on the mind is a waste of time.
