As we know,google update pr every 3 months.. Last time google has updated at Novermber 7th...So It has a about 10 days. There are many link seller in this forums ,they want to get a good price for their link base on high PR. But as we all know that google will give high pr for thoes sites which update regularly and have high quality article.If you want to sell a good price,you must keep on updating high quality article and do not add a lot of links or ads in your sites.. But as a seo,I think PR is not important....Buy and sell links maybe will banned by google or just penalized by google when google found..
Its been only 2 months since the last update but you never know, Google can bring an PR update any time now. But there have been so many updates in the search algorithm updates even after the last PR update.
Last we didn't find any imprevement in PR. But we are good at our seo process now. so we are expeting some improvement in PR, Hope along with those page rank changes there may be many changes in alog ...
