Second: At this time, there is NO real and/or material evidence that any other exchanges have been engaged in fractional reserve banking or stealing money or security breaches at any level near what seems to have happened with GOX. And, if audits do take place, and some of these problems exist (which is likely), there is NO evidence that the "problems" are at any level near the GOX situation.
Well... none of the other exchanges has volunteered to give even a rough idea of their financial position, especially how many BTC they owe and how many BTC they own.
I count that as "real and material" evidence that they must be in some sort of Karpelian situation themselves.

Just not true. Serious academics shouldn't make such statements - baseless assumptions that a couple of minutes of research would completely debunk.

etc.
Personally, I would NOT be surprised if there are many discrepancies in various exchanges; however, at this point we would be engaged in a high level of speculation to assume that any discrepancies in other exchanges (such as Bitstamp or BTC-e) rise anywhere near the GOX level of incompetency and/or fraud.
