Scoring
How many questions did you answer correctly?
0-3: You are pretty bad at Facebook. You are either trying not hard enough or way too hard. I know Facebook is kind of a world unto itself, but that doesn't mean you can dispense TOTALLY with common human decency. Also, know your audience! (Mostly your audience doesn't care, except in weird cases where they really, really do. Your audience is tough to figure out. But it wouldn't be that hard for you to do better than you're doing now.)
4-7: You are kind of bad at Facebook. The good news is that almost everyone shares your condition. Everyone is so awkward and uncomfortable that every Facebook-related decision you make is like tossing a coin. Is THIS going to be the status that gets you more than 10 likes? (And with it, a full thirty seconds of joy?) What about THIS one?
8-10: You're not that bad at Facebook. Is there a real way to be GOOD at Facebook? I don't think so, anymore. It's a sliding badness scale, and you're doing as well as any one person who uses Facebook really can. You've got a pretty good handle on how much to say and when. Don't let this go to your head. Don't post a status about it. (Do.)
