@callmejake someone explained it like the email servers we use. Some people have Hotmail some people have Gmail, etc, but we all can talk to each other regardless of the server.
@michealsandbank debirdify helped me see who was on Mastodon that I had been following on Twitter. But, I'm still lost as to where to find people to follow. Disclosure: I'm only 3 days old in Mastodon years :-)
@SpockResists am staying, but not sure in what capacity. This has been a difficult transition and rebuilding a followers (and following) list is daunting.
