There is very clearly many things wrong with this when the things being shown require very little skill or effort.
That is by no means all of these projects. I'm not interested in a circle-the-wagons crackdown because it won't work (see "it's foolish to fight the future" above), and because we should be welcoming and educating new users in how to contribute substantively to HN.
Taking a good picture requires very little effort once you've found yourself in the right place. You gonna shit on Ansel Adams?
Why exactly is the skill level required for something a gating parameter?
