It looks like a huge amount of hashing capacity joined the network in feb:
http://bitcoindifficulty.com/This seems to have preceded the current price run by 6 weeks or so. Did a lot of people get into mining at once? I was under the impression that not that many ASICs had been released yet, and this is a tripling of hash capacity since 2/1 and now. Is there somewhere to see the total number of nodes on the network? I'm curious as to how that hashing capacity is spread out.
I assume that at the very least the pools would have that information... is it aggregated anywhere?
