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.
Oh sweet. Might try it again.
I’ve yet to even get the lemmy frontend successfully running for development. Maybe piefed will be easier
