I joined as the #TwitterMigration just started. My instance was just a few hundred people as I learned the ethos here (e.g. #UseCamelCase, #UseAltText, #BoostNotFavaorite, #UnlistedPostsForThreads, #UseContentWarnings---still working on that last one).

At first I impatiently waited for more people to move over so I could replicate my previous way of internet-ing over here, but meanwhile I got a glimmer of the #BeforeMigrationTimes and understand what people had built how they interacted.
