Ourglass is a social networking platform that only allows each user one post per day. After 24 hours, the post disappears. This restriction forces content creators to put out the best piece of content they possibly can every day.

BUT... There's a catch.

Though each post by default has 24 hours until it's gone, if the post receives more likes than usual, each like will add a small amount of time to the post (like adding sand to an hourglass).
