Is Tycho an unbiased person to ask? No offense Tycho, but you get 3% of his massive input which is quite considerable. Also, to be honest, I am getting nervous about the size of the pool. Tycho has already said he is investing in mining hardware with his earnings. There is a lot of potential for corruption. I don't believe that Tycho would do this, but having such a large pool and still growing is getting scarry, especially since it is rapidly approaching that fearful 51% scarey.
I am not trying to discourage people to use deepbit, just from allowing it to overcome the bitcoin market.
Tycho's already said that he doesn't plan on taking more than half of the total Bitcoin network over (though I don't know how he plans to mitigate that)...if it gets close, no offense to Tycho, but I should be moving on. It's all about the security of the network.
