Congratulations to Mike Arrington! It's been said that you haven't truly lived until you've moved the stock market, and with Yahoo's intraday spike today, Mike must be feeling a new and previously unexperienced sense of accomplishment.
All joking aside, the comments section of the market moving story includes everything from random web visitors attempting to discredit Mike, to someone personally thanking him for manipulating the market.
What's all this add up to? More publicity for TechCruch, of course! I personally saw CNBC give them a mention live on air, so I suppose they win whether their sources are credible or not.
