Not an engaging topic apparently.
My take: I'm a little ambivalent. On the one hand, it seems a bit pandering to the lowest common denominator. It's like Chess Dot Com felt some users would find diagram-style pieces strange and confusing prompting them to create a set that looks more like physical pieces. On the other hand, I'll admit it is a pretty clever design compromise between looking like physical and diagram sets -- much better than, say, Yahoo pieces from back in the old days.
I'd never use it though.
Obviously, people can choose whatever set they prefer, but what do people think about the default Neo piece set?
