Umm... yes, I've heard of "TheFacebok.com." Myspace was just getting popular my freshmen yr of college thank you very much. (You don't have to be a patronizing d-bag, btw.) I think you're STILL not getting it. It does not matter whether or not Google Groups is newer or older than Facebook. That is irrelevant. The OP is asking whether FB is helpful as a medical student. It would be ridiculous for him to start a Google Group and then get up in lecture one day and announce to the entire class that, "the new online forum for our class is a Google Group, just go to groups.google.com/xyzsom2016," because no one would do it. They would stick to what they're comfortable with. It doesn't matter that Google has a better system (honestly, this is not the least bit surprising to me). You're arguing for the sake of arguing, dude. Get over yourself.
