@dangillmor I use a variety of sources: @mastodonusercount, fediverse.observer, the-federation.info, and https://beta.fedidb.org
Short answer: there's no slump.
Sign-ups continue to increase -- albeit, not at the same rate as in November -- November was a spike.
While MAUs decreased since November, it's increased again this month (according to @Gargron).
But what's more interesting is that HYAUs is at a peak.
And we're very close to breaking 1 billion posts per month!
See chart.
@dangillmor But this chart for Misskey is even more interesting to me. This is
Average Misskey Total Users by Month.
The growth is absurd -- and it has been validated by multiple sources.
Misskey is part of the Fediverse, and it talks to Mastodon.
