When studies contradict each other...

...I usually go with the one that makes me feel better. So here's a study that says Facebook users have lower average grades. And here's one that says that, with the exception of internet addicts, people who do a lot web surfing during their breaks are more productive at work. I'm going to go with the second--all this surfing and posting makes me more productive at times since I tend to use web-breaks and blogging as mini-rewards for accomplishing tasks. This post, for instance, is a mini-reward for finishing writing part of a final exam.

(And yes, I realize that these studies don't actually contradict each other at all.)
