A quick addition:
I'd like to emphasize that it was the *domain* that was hacked, not the site itself. There's no indication that the hack went any deeper than the filesystem, while your account information is stored in a secure database outside that file system.
Even if that weren't the case and the hackers did have access to the database data, your information is encrypted very thoroughly and the database would be of no use to the hackers.
Your information is safe.
And again: I'm on the motherfucker.
