Googlebot pranks stock market

Notice anything funny about this chart?

At about 10:45AM on Monday Google listed an article about how UAL had just filed for bankruptcy. This news was automatically picked up by services that piggyback on Google and was propagated all over the web where it was then picked up by automated stock-trading systems. The stock price fell by 75% in a matter of minutes.

The thing is, the announcement was six years old. Google discovered a copy with no date on it, apparently because it appeared on some generic "recent popular links" list, and threw it into the news hopper anyway. Over a billion dollars of value temporarily disappeared before NASDAQ hit the emergency brake.

Google=the singularity
