That's a very good point. I think I phrased it that way because I believe it's part of a bigger issue at hand - namely that we have all these things reinforcing our bad habits and bad traits, and we don't really pay attention to it since it's so ubiquitous. I can't think of many technological solutions to these types of problems - I say that because trying to ban those types of software generally is like playing whack-a-mole. You get rid of one and another one pops up. The real solution is that people have to police themselves when interacting with technology - being judicious. I wish there was a good way to make that part of our culture. Reading "Here Comes Everybody" is what inspired this line of though in me. Edit: Especially since reading through the rest of the article: what's happening on NextDoor was happening on other sites: email groups and yahoo groups. I think there's bigger hubbub about next door because it's more visible.
