@atomicpoet I joined mastodon.social in 2018, when "big" was a relative term and the small instances were in the single digits for members. (I suspect many of those have gone the way of the dodo...)
Not planning to leave. Hey, I got a cabin on the mothership in the early days! But I have since joined another instance under my name, one under a pseudonym, and pixey.
For now I'm staying flexible, paying close attention to how things evolve.
@Karen5Lund I'm not planning on leaving either, but I've created a back-up for when this instance has fits. That said, I've also started several instances for other folks to use.
