It’s now clear that the Reddit blackout will have a significant impact on the platform, but perhaps not in the way its organizers intended..

From the article:

Meanwhile, the blackout has affected Reddit in other important ways. There’s been a small, but growing push among some power users to federated Reddit alternatives like Lemmy and kbin. These decentralized platforms are still niche, and have many of the same challenges as Mastodon and other Twitter alternatives. Yet there seems to be growing interest from some corners of Reddit in recent weeks.
