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.
