Isn't it strange difficulty is so high on launch with only cpu miners... and a "broken" cgminer in github??
what did you say?

Are you running that with the --keccak option? I can run it with --scrypt but not keccak.
I'm on linux btw and compiled cgminer with --enable-keccak and --enable-scrypt but it hangs when I run keccak.
Did you compile the source?
Christian put out a release today for keccak. Dusted off my old 580s... but not getting any blocks...
