......Hell no.
First of all, I can't be with my Girlfriend for a year? That's absolutely not acceptable. Second, I can't hang out with my friends for a year? Not worth it either, I'd go nuts from boredom/lack of companionship!
Three, NO INTERNET?! How am I gonna play my Steam games? How am I gonna get my fill of Zero Punctuation, Extra credits, and all the other good shows on the net?!
Plus, the showmakers would probably try their damn best to force us to cause drama and stuff so that there are more views!
So that alone turns me off the whole thing. Now onto the whole zero privacy business...It would suck for me. I'm a bit bizzarre, and I'm sure that if I DID participate, the world would forever remember me as "OH YEAH! You're that retarded guy! The guy who sometimes talks to himself about random stuff! The guy that they caught fapping one time made a big deal about because a nerd fapping must OBVIOUSLY mean he's a pervert!". >_> I would not enjoy that.
And FINALLY, I would probably be inevitably drawn into some kind of drama. Possibly, a female neighbor would want to get someone else jealous and try to use me, and even though I'd turn her down, the showmakers would probably make it look like stuff happenned and then play that up for all it's worth. I'm sure my GF would see through that, but I'm not so sure about the rest of the world/people we know. Oh, and the jealous guy would either beat the shit out of me, or start effing up my life.
So no. I would not do it. It's not worth the money.

If you'd want me to participate, you'd have to do several things:
1) Allow one day a week (or if I'm being generous, one day every two weeks) where the cameras are off and I can have visitors (girlfriend, my friends, etc).
2) Allow internet. That way I can keep up on the new gaming news, waste time on TVtropes, and maybe even do a blog-style let's play of Civilization 2 since I'll have the time. Also, it'll allow me to have my weekly fun on Borderlands with my buddies.
3) Allow us not to use our real names, so we have less chance of being noticed and mocked after the show.
IF that's done, and I can bring as much of my own stuff in as I want, then sure, I could deal with that for a year. But otherwise, hell no.
