hmm, I see lots of people talking about a pr update, but it certainly didn't hit my sites. I have six pages that have higher pr sites pointing to them, plus coop links pointing to them, and I certainly expected increases during the update..... but 'nothin for me I was looking forward to more coop weight. At least my serps continue to do well. .
Join the club.. A bunch of PR5 and PR6 links back to me, as well as tons of PR2/3 sites linking back, and I'm stuck at a PR3. Doing well in MSN/Yahoo, but barely visible on Google. Strangely enough, one of my KW's that I target solely through the coop, finally showed up on Google's radar. Still in the 100s, but considering no "real" links point back to that phrase, I'm pretty jazzed by it.
Do not worry about PR update. In addtion to the linking factory just make sure to handle many department of SEO .Thisng will improve.Dependence only linking mechanism is not all about SEO
