How Much Time Do You Really Spend on Facebook?

If you're a Facebook addict like me, you're spending 125 solid hours a year on the site - the equivalent of more than five full days - according to a new study from Nielsen Online.

I don't know about you, but that number sounds low to me. Between all the thumbs-ups, status updates and games of Word Twist (I know - I'm a dork), I probably spend, like, half of my waking hours on Facebook.
