I’m noticing the rollback to before the last update and the current PR readings across the multiple datacenters. No new PR is showing. Yes, Google has been working in strange ways the past few months, they have rolled back to old results several times for days at a time.
DealerDan, not to burst your bubble, but you can achieve a PR3 with a few days worth of link exchanges. PR3 is very easy to reach. PR4 takes some good effort. PR5 takes a ton of dedicated effort. PR6 is very very hard to achieve, and is nearly impossible though simple link exchanges only. PR is a logrithmic calculation and it takes an increasingly more difficult amount of work to achieve each level. The good news is that a PR5 should be all you need to compete fairly well.
