I really enjoyed Go until I started trying to work with interfaces. The fact that you have to understand the implementation details at this level in order to use them reliably, IMO, shows that when the Go team talks about language simplicity, what they really mean is _compiler_ simplicity. At some point, the complexity starts getting offloaded onto the end developer.
That said, the fact that the crowd only offered an incorrect guess four times out of 16 is telling. This really didn't have the same feel to me as the original WAT talk, which is really full of truly strange things.
