Downvote it. Ignore it. Say "HN will down vote useless content" if you like. But mentioning another community will attract downvotes. You are insulting users of those other communities and there are often overlaps between users of them and HN.

By mentioning another community you are turning it into a "Team HN" thing. And that's something that you suggested was bad.

OK. The team thing is fair. I was attempting to contrast the sort of content I usually see here with 4Chan-type content (and I don't really care if that is insulting, if it is true), but you're right. I would downvote the post if I was able to. Alas, I suppose I'll ignore it.
