Comment Policy: We'd like the posts to be civil, of course (no profanity, personal insults, and the like), but we're also hoping that people try to be as calm, reasoned, and substantive as possible. So please, also avoid rants, invective, substantial and repeated exaggeration, and radical departures from the topic of the thread. Sticking with substance -- and staying on-topic -- will make the comments more helpful to other readers, and more pleasant.

As editors, we reserve the right to delete posts, and even to kick out posters, though we hope that both of these will be exceptional events. (We also reserve the right to be busy with other things, and therefore (1) not remove all the posts that might merit removal, and (2) ignore demands such as "You should remove A's posts, because they're just as bad as B's!")

Here's a tip: Reread your post, and think of what people would think if you said this over dinner. If you think people would view you as a crank, a blowhard, or as someone who vastly overdoes it on the hyperbole, rewrite your post before hitting enter.

And if you think this is the other people's fault -- you're one of the few who sees the world clearly, but fools wrongly view you as a crank, a blowhard, or as someone who overdoes it on the hyperbole -- then you should still rewrite your post before hitting enter. After all, if you're one of the few who sees the world clearly, then surely it's especially important that you frame your arguments in a way that is persuasive and as unalienating as possible, even to fools.

Our goal is to provide an interesting and pleasant environment that can help inform readers. To do that, we'll occasionally have to exercise our editorial discretion. Think of this as an in-person discussion group, where having different voices is critical to a great conversation -- but where sometimes the leader has to deal with cranks who sour the conversation more than they enliven it.

Naturally, there's always a risk that this discretion will be used erroneously, no matter how well-intentioned the editor. But discussion groups (especially on the Internet, but also off it) generally need an editor who'll occasionally make such judgments.

And, remember, it's a big Internet. If you think we were mistaken in removing your post (or, in extreme cases, in removing you) -- or if you prefer a more free-for-all approach -- there are surely plenty of ways you can still get your views out.
