To my dismay, the trajectory of Show HN posts looks eerily familiar. ProductHunt followed a similar course (albeit with much more acceleration) and now is just a feed of slop. The signal to noise ratio became so meaningless that I lost all interest. I fear this happening to HN. Any attempt to slow this down is welcome.

I wonder how will this review system work. Perhaps, a Show HN is hidden by default and visible to only experienced HN users who provide enough positive reviews for it to become visible to everyone else. Although, this does sound like gatekeeping to me and may starve many deserving Show HN before they get enough attention.
