Sometimes I wish I was the only gatekeeper. It's better though that I am not, I was wrong on so many different things back in the GLBSE days that I when I setup btct.co I knew I needed to get other people involved somehow. I really hope they're right on this one.
Are there any plans or thoughts so that in the future any companies or other entities which wish to be put on your exchange will be required to be vetted first? Or will it continue to be a wild west sort of situation still?
Depends on your definition of vetted. I'd argue that we're one of the harder ones to get listed on at the moment. Aside from MPEx we certainly have the most documented minimum requirements. (Check out the Asset Issuers ToS.)
