Similar to Mastodon's spikes last year, it seems. Anyways, there is data to think about. Source
For the last month and a half, I have not used reddit at all. Lemmy has most of the communities that I was a part of.
But I get that, some niche subreddits still don't have communities here on lemmy. A few of my friends, stopped using lemmy because it didn't have the subs they were active in.
