This is (maybe) the “beginning” of the end for Reddit, not the “end” of the end. The big change isn’t Reddit, but here.
When Digg fell, everyone moved to Reddit. When this API situation started there was not an obvious new solution to move to. Lemmy/KBin were mentioned but not readily accepted due to concerns with the content and capabilities of the fediverse. That is changing quickly, and the next time Reddit screws up, we will have much more active communities, quality apps, and fewer bugs.
Worst I’ve seen was “ruffies”, best was “lovle1”
