How Obsessed Are You with "Big Brother"?

"Big Brother" kicked off its eighth season on CBS this week, with some of the houseguests discovering they'd be sharing their living space with someone from their past. I've always thought "Big Brother" made it easy for fans to get hooked, what with the three weekly airings, the 24/7 access to the house and this year's addition of "America's Player," which lets viewers decide what one person in the house does. So, I've got to ask: How obsessed are you?
