Maybe it's time to sign off the social and start studying, hmm? A recent study examining the academic impact of Facebook has shown that people who use the site on a daily basis are more likely to earn lower grades than their peers — as much as whole letter grades!

The inevitable conclusion is that the site is a big time-waster (although I've noticed I spend less time on Facebook since its latest redesign, so thank you for that time back, FB), causing students to sacrifice the time they should have spent studying.

The Internet itself is an addictive place, but what is it about Facebook that sucks up our time so much? Are we just curious about other people, or are we all just narcissists? Either way, we could all use some Facebook breaks — after all, it'll all be there tomorrow.
