Guys, relax. PR will not boost your serp positions. Ok, is great to have it but .... i preffer to have pr 0 and first positions on my keywords
Well, it depends on competetion. I have also 0 PR site with great positions in SERP but only becasue nobody cares about that theme
Those who are not getting any PR update, its a factor of numerous things. As we know repeatdly on dp members point out, that posting higher PR creates more visibility.
seems, that its not happening yet, its about every 3 months, but sometimes, i see, that my sites, get Pr between updates. Just FYI: I have site with PR 6 and i link my other site with Zero PR, new site, in a month or so, new site gets PR5, so, this example shows, that PR means almost nothing, because, my new site dont have any traffic, etc. so, PR does not always mean, good site or authority site.
