Henry Blodget, of alleyinsider.com, has been harping for weeks on signs that the Internet economy might be headed for a downturn, starting with a drop in mortgage ads following the subprime real estate loan blow-out. Now Nielsen reports that the top ten Web advertisers dropped spending September.

Haven't spotted this much elsewhere, but Blodget has been making a good case.

interesting and scary, but it seems like the bust will occur on a smaller scale this time, more of an adjustment... wait for web 3.0 which will be mobile centric and quality content driven.
