A much bigger discussion: https://news.ycombinator.com/item?id=7890215 It isn't hype, a 51% attack is a very serious breach of confidence.

Already read it, I'm in the comments on the blog entry a couple times. If GHash were actively exploiting this advantage I'd be saying the same thing but they aren't and there's a high probability that they never will.

It's worth nothing that you don't need 51% to attack bitcoin , there are some probabilistic attacks for adversaries with smaller share in the network.

Exactly -- This whole thing is just over-hyped IMHO.
