100% from home.
I'm online briefly in the morning before I go to work. I've got an outside job, so at work isn't really an option.
Then, when I come home I'm sometimes on briefly, but most of my time is done after supper (6:30pm PST /DST).
Also, I split my A2K time with a chess site that I've been on since 1999, but more and more time is spent here.
