In general, moralizing sucks. It gets especially annoying when cultural commentators talk about how much society has changed, for the worse, with the advent of technology and the internet. Ezra Klein:

So if you're someone who likes to spend Saturday in a quiet room with a good book and a long time to think about it, you might find Facebook unnerving. And Zadie Smith and Ross Douthat do. Sometimes, I'd guess, we all do. Conversely, if you're someone who likes people but has trouble meeting them, or gets shy in unfamiliar social settings, you probably don't think the Internet has made you less human.
