Ok, this is interesting in a "inside Google" sort of way. TechCrunch reports that Google has launched a de-ranking offensive against blog link farms. This is a good thing, because search results will often take you to these bogus sites rather than the original content source.

However - as with any such battle, it looks like there's been some collateral damage:

The AOL owned Weblogs Inc was not immune, with leading Gadget blog Engadget dropping from PR 7 to PR5, Autoblog (6 to 4) and DownloadSquad (5 to 4).

That caught my attention, because the PageRank of this site is a decent 7 (scale of 10). It's just weird for my blog to have better PageRank than a site as popular as Engadget. I suspect that this move is going to create an awful lot of tooth grinding.
