Gregory's Server@J12t Fair question, I guess it depends on how Threads is counted amongst this, as Fediverse adjacent or not, but I think this still holds true with a qualifier or two.
The various posters of the #fediverse stats seemed to indicate the growth was a) significant and b) real, so ... close enough for a high level statement.
@drimplausible Well, I don't know, for example, Meta as a whole in their earnings report just reported record MAUs across all of their products. I would expect that most Threads users were existing Instagram users, so they don't count as incremental MAUs, and so I would expect that user growth for Meta products was larger somewhere else than for Threads.
