I'm not too sure about that..let's pretend MtGox accepted almost every altcoin out there. I think that'd discredit them in the eyes of the mainstream, and this is critical if were ever gonna see these types of ideas reach significantly beyond these forums/niche audience. Because after all, the mainstream doesn't share our view of the free market as we know. However I would agree with exchanges setting standards that people should adhere to concerning cryptocurrencies. Of course this would all be voluntary, and if an exchange wanted few or no standards, that's fine too (just think of bter "spreading its legs" and being "slutty"

However I'm sure plenty of us know that
