Once you dispense with need for superficial "niceness" and "profesionality" and consider things rationally, you may find out there's a strong reason behind how MPEx does things.  Both Bitfunder and BTCT I perceive are doing their utmost to be nice,to cater to  everyone...and I fear they'll spread thin and it will be their undoing. Or maybe not I hope, they are nice folks.

Oh and MPEx was reaching 50k/mo volume long before satoshidice, due to their in-house BTCUSD options trader-MPOE. Many ignore MPOE at their detriment.

Edit: MPEx publishes its database,too, in encrypted form. Just releasing a GPG key will be sufficient to decrypt it.
