PieFed gets /r/random, like reddit used to have

Piefed a un boutton pour découvrir de nouvelles commu :)

You’ll get taken to a random community. Once you arrive there’s a link at the top of the page to /r/random so you can just hammer away at that until you get somewhere that’s the right combo of random and interesting.

There is also /r/randnsfw that takes you to a random nsfw communty if your instance has them.
