It's funny how big shots like facebook spend 1 billion dollars on Instagram which have no revenue and companies like PayPal can't spend the same amount on a proven profitable business model like a bitcoin exchange.
For me the only way out is Gox being acquired by some big company. This does not seem too hard considering they would need something like 600 million to clean up the alleged mess and start fresh.
EDIT: Also acording to that leaked report the Gox annual revenue is superior to WhatsApp which was bought by facebook for 16 billion.
http://www.quora.com/WhatsApp-Messenger/How-much-revenue-is-WhatsApp-generatingthese things are completely different. The growth opportunities of these companies are completely different.
Not to mention buying a bitcoin exchange would be like buying an elephant. Sure it might have a steady stream of revenue from visitors who want to see but if your business isn't in the animal business then feeding, housing, and all the other issues an elephant brings on won't make it worth it for the peanuts. Unless you are a zoo or circus of course, then you might do okay.
So no, facebook, google, or any other big name company outside of finance, and a narrow niche at that, don't make sense.
