Steve Ruble points to an interesting fake blog occurrence - where whoever is behind the fake blog is spamming negative comments about the company in question with positive spin. Fake blogs are getting more common - take a look at the results of this Google search on the term. Of the supposedly 10 million + blogs out there in the US, I wonder how many are either:

• Dead (i.e., one post and gone)
• Troll blogs of the sort I mentioned above

One things for sure - it'll be really hard for search engines to filter this out - not least because the service being abused most is run by Google...
