Sorry, but that site does not represent actual shorted shares...and it certainly isn't short interest. You need to learn how trades are reported--only the first leg of a trade is reported. Often, it is an MM going short to facilitate the trade. But that is covered immediately, in most cases.
Common sense indicates that no one would dare to go short when a stock is going up the way this did today. Going forward, if anyone used common sense, they could see that shorting this would be a slam dunk, if there were shares available, or an orderly market for shares. Niether is present, however....imo.
Watch for this to drop back and calm down soon.
