Be that as it may, you should still not post lame one-liners. That's still just obviously lame and you get sensibly scolded for it because it makes the site worse, orthogonal to unified theories of voting you may have developed.
Disagree. It's not particularly lame. A well written one-liner conveys more information and wastes less time. Maybe HN could have a "vetted user", somebody who generally plays by the rules of the site, so that people can see one-liners and know the person making them has the authority to say it.
It's totally lame and the example is, indeed, perfectly lame. But there's a trivial way to make these good which, if you look at dang-scoldings of lame one liners, works surprisingly well for a huge number of them, not just yours:
Write the one liner and then imagine you got a moderator scolding.
Then write a comment defending your one liner from the charge of 'unsubstantiveness'. Finally, delete the one liner and post the defense.
I bet you'd almost never get scolded for these and the upvotes would be even bigger.
