Actually, not only is Wordpress a donkey with wings (and hefty balls) but Google sets a preference for Worpress blogs over its very own Blogger. Shocked? I speak from experience. My acro.net blog might be fresh but I've been blogging on several Worpress and Blogger blogs since 2005. For the same keyword search, Wordpress ranked higher and earned a
PR much quicker. One of my Wordpress blogs is not even six months old and a PR3 already. As I said earlier, Wordpress by default pings several points of high authority, such as Technorati which yield more relative results faster at Google. Incidentally, Google has started to not only favor blogs with content over static web sites but it has been dropping the almighty Wikipedia from its top results.
