The UI is interesting but it's almost a brand new forum.. it's really hard to get a forum to start if there are already much larger ones discussing the same subject.
I wont much disagree with the fact that BCT forum has more topics related the bitcoin as a currency rather blockchain as a technology.Same resemblance can be put forward for shapeshift and other exchanges.Shapeshift is decentralised so it is huge potential in bitcoin community but also there are many exchanges who uses primitive platform of trading with usual signup thing.
