It's a shame, I used this exchange a bit and really liked the interface and some of their blog posts, but they never really seemed to attract much volume. I'd speculate they were partly overshadowed by other new US exchanges like Coinbase.
Agreed. But I never saw any promotions by them to attract new users. Even here in Bitcointalk, I hardly ever say any of their offers or discounts. Accept the truth. These guys were not interested in running the site. Their intentions were something else.
There were definitely promos but perhaps they weren't advertised well enough. They had a referral program with signup bonuses, as well as no fee trading (which was slightly misleading as there was still a fee on the bank transfer to fund your account).
