This quote tells you how sloppy the journalism is:
"Even so, Bitcoin is vulnerable to massive theft, fraud and scandal, which has seen the price of Bitcoins whipsaw from more than $1,200 each last year to as little as $130 in late February."
The MtGox price in February was meaningless, a more accurate representation would have been $1,200 to somewhere around $500 that reputable exchanges were selling for (I don't know the actual price, just enough to know that his figures are misleading).
The Mt Gox price divergence actually makes her point stronger. she's highlighting the volatility, and the failure of a major exchange is pretty volatile.
The ~$130 price was on BTC-e. It was very short-lived, and was caused by a very large dump of coins that were bought up by a bunch of bots, which met all the standing buy orders from ~$680 down to (if I remember right) $102.
The price immediately rebounded to the mid-$400's, once that order was consumed.
