We've seen a recent PageRank up date this week. One thing that people have been noticing is that some of the home page PageRank is lower that their internal pages.

There is a discussion underway here at search engine watch on the topic. View Thread >>>

I personally brought up 3 points that could be the reason. They are as follows:

• Advertising links not using the rel="nofollow" tag, and being off topic
• Better Link Popularity on the internal pages
• Just another one of those wacky glitches

What ever it is, it hasn't seemed to be messing with rankings on any of my personal sites. Webforgers.net being one of them.
