@mastodonmigration Yep, and just like email you use the full address (including the @ domain name/instance) when contacting somebody else, you can communicate with other domains/instances from any other (bar blocklists/spamlists) and you could just have one email account/Mastodon account in the world or multiple dependent on preference (work, social, special interests etc). Once you imagine Mastodon as "instant public email", it makes it a lot easier.
