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.
