@gulfkiwi @BeAware The reasons I've been given/observed: a more familiar interface (it looks more like Twitter); easier to get started (it has a few nice onboarding features that Mastodon does not); less nerdy; less scoldy and lecturing. Those last two come up a lot. Seems many people joined Mastodon, found it to be quite severe in tone, often getting "scolded" (that term comes up a lot) for various things. The experience on BS is lighter in tone; more liberal and forgiving.
