Reddit is Dead, long live⦠leddi- lemmy?
Earlier this year I s/twitter/mastodon/ to good effect. I don't think s/reddit/lemmy/ will happen anytime soon; the numbers are too small for any real network effect.
For example, the subreddit I spend the most time in has >2million readers. There are enough posts daily that my niche interests come up regularly and I contribute to those discussions.
