According to https://fediverse.observer/stats we are currently at ~6.4M-7M users.

So, if Matt Mulenwig does actually get his engineers to add #ActivityPub support to #Tumblr, the whole #FediVerse and #Mastodon could be in for a massive culture shock.... The best stats I can find (https://financesonline.com/number-of-tumblr-blogs/) Suggest there were 29.4M users of Tumblr in 2020 with ~%8 annual growth rate, or nearly 35M users in 2022.

That would make the Fediverse jump to ~42M users.

GULP.

@Unatributed I wonder about active users though, certainly the fediverse has more people I know active on it at the moment.

It's hard to imagine a culturally better fit than Tumblr among the mainstream platforms, so I am optimistic about this.

@john as to the quality, we'll have to see. I think Automattic has made some changes to their migration that might be good, but I took down my blogs on there in January, before they'd made a lot of changes.
