No problem Alan. I knew this question would seem like the typical, "Can I rank from PR links," question.
Honestly, that is why we have never used these sites. In theory, if these site were used correctly, I think they might be valuable, but the amount of spam and hopeless SEO's that post useless content for a face value link, seem to bombard any hope of usefully content every being found or trusted by editors and writers.
I just wanted to check and see if anyone has ever experienced the opposite and had a real story or blog post come from their press release being found on a PR site.
