UPDATE: As of this morning there are now more than 7 million Mastodon users, most from the #TwitterMigration.

In fact, 100,000 new accounts have been created since last night.

Since last night's spike 8,000-12,000 new accounts are being created every hour.

Yesterday, I estimated that Mastodon would have 8 million users by the end of the week. That might happen a lot sooner if this trend continues.
By the way, if you're wondering why I'm posting from this account rather than my usual mastodon.social account, it's because mastodon.social is about to give up the ghost -- and as I told all you, it's best to have a back-up account and self-host if you're able.
@atomicpoet I believe these big servers really should be hard capping the number of users they support. There's thousands of servers on Fedi. Let's use them effectively instead of dogpiling on just a few because they are popular.
@anji Exactly.
