I thought the higher pr the better eg. pr1 is best, then pr2 etc etc Dude ... according to your example ... PR2 will be best then PR1 .. You can consider PR stars ... 2 stars are always good in comparison to 1 star .. isn't it ? But i just came across a thread buying blog posts, the lower the pr the more he pays According to me ... You are confused ... you are saying High PR as Low PR and Low PR as High PR I think its enuff to let u know how the value of PR counts .. let me know if u still have something to ask .. I will also like to request all DP members ... Instead of increasing post counts.. understand what exactly the guy is asking and then only reply ... if you feel that you are not getting what the person is asking don't reply !
For pricing calculation its also essential how many outgoing links are on the specific page. So a PR2 with only 1 outgoing link is maybe more expensive than a pr4 with 20 links.
