having recently acquired a facebook, my current answer is probably an hour or two a week. My interaction with facebook is posting links of stuff I'm releasing (which, at the moment, has a target audience of people at my uni, when this project is more general, I'll post it on HN), answering friend requests, and answering messages posted to me.
Of those three, two of which I do after facebook sends me an email telling me either "hey, this guy requested to be your friend", or "hey, this guy sent you a message, here is the content: [...]".
I also spend approximately zero hours, and I regularly check my account. I just don't use it for anything but what it was originally intended for (back in 2004) - keeping up with actual people. I get a lot of value out of its original purpose and I see virtually no benefit to things like 'pages'. If that counts as "not using Facebook" then no, I don't use Facebook.

HN and one anonimous forum - is all I can do.
