There will be a spiritual successor though, for kbin/Lemmy, called Artemis: https://kbin.social/m/ArtemisApp

Right now it's in a closed beta, and the size of the closed beta is increasing slowly through the end of the month. The goal is for it to be public around the start of August. That kbin magazine has a link to a signup sheet for the closed beta.

(disclosure? I was an alpha tester for it, and so far it looks AMAZING. The dev is awesome, it's a really friendly community, and the amount of progress in just 2 weeks of development is really impressive.)
