It's obviously pretentious to tell people what to do on a site like this, but one of the things I notice about HN is that we seem to reward good answers much more than good questions. But without the right question being asked, that answer might never have been written. Vote up comments that lead to good answers and good discussions, and maybe we'll get more of them!

The flip side is that sarcastic one-liners often lead to a string of similar responses. Usually the piling on gets (properly) voted down, but the first joke often gets a lot of points and appears high on the page. This isn't necessarily bad in itself, but when posting a quick quip stop to think ahead of how people will respond to it. If it's going to produce a string of low quality rejoinders, maybe it's best to skip it.
