I'm finding that there is no harm in having a birdsite acct. per se. But having a Mastodon account or two is good too,
@seth I think the best approach is to post to Mastodon first and use a cross-posting tool to syndicate to Twitter. Use BirdSiteLive instances to follow some Twitter accounts but primarily interact with Twitter only when you receive a mention/reply.
A podcast instance of Mastodon. All, appropriate topics allowed, but podcast topics happen a lot.
