>The other big question on Ether (for me) is the talk about going from proof-of-work to proof-of-stake. That sounds like something that would sharply cut the price of Ether, which is good if you want the network to actually be useful, but bad if you are a speculator.

Why is that? I'm pretty uninformed on this stuff...I get that POS basically replaces risk via electricity cost with risk via an Ether stake...but I don't get how it changes the supply or demand...
