What!?

So the fact that a "typo" could make the stock market lose 10% of its value in less than 5 minutes should be more than a little frightening. The guy typed "billion" instead of "million", which is equivalent to what would happen to my checking account if I typed "thousand" instead of "hundred" when paying my electric bill. Of course we are expected to say "oh dang" while our 401Ks hit the skids. I wonder if my bank would do the same if I made the "typo"...
