Google's kicking their own ass
Not only is PageRank dead and messed up (despite discussions on Webmaster World about redoing the algorithm), but now if you search for "search engine" on Google, it comes in fourth-place behind AltaVista, Lycos, and Yahoo.
I do know the Google's hitting older pages on my site more than newer sites, and my rankings haven't been as good as they used to be. Call it whatever you want, but I call it the "Blog Penalty". Before too long, I wouldn't be suprised, because of all the pressure Google is under, if Google starts sending blogs down hard in the listings.
