People who are like "The migration to Mastodon has failed!"

No it hasn't. I literally migrated to Mastodon from Twitter, and I don't use Twitter anymore, but I do use Mastodon every day.

I call that a successful migration.

@rasterweb Mastodon has worked 10x better for me than Twitter, which often felt like shouting into silence, even after a decade. I’d call that a success.
@linux_mclinuxface @rasterweb very much this! Posting here results in conversations. That stopped being true on twitter in like 2012 for me. Fediverse feels like early days of twitter, but biased towards people who believe in the platform and have a general overlap in ideas or interests
