Lots of people are buying PR4/5/6 links... sometimes even lower PR if the price is right. Give them something worthwile and you'll sell those links. If you don't try, you'll never make it.
I bet google will fix this glitch with the last update. I think its only PR0s that got to PR5 and higher. Someone on DP also went from PR0 to PR8 with a few low backlinks. When it comes to selling links i personally check the backlinks anyway. If they dont quite add up i wont buy the link. Who cares what you green bar says especially after the last google glitch. Same goes for link exchange... dburdon I dont think so. Its just a glitch. Those sites that got high PR for no reason did not jump in SERPs. rahman15 Just keep your site, carry on developing backlinks etc and then when you have some traffic... make money from it.
