One thing I've been noticing about Mastodon[0] is that it is incredibly easy to segregate your personal, political, and pastime posts, trivially by having multiple sites in multiple browser tabs, but even better with a client that supports multiple accounts. You can tie your different identities together through your profile, and import/export your subscription lists between instances. And everyone who follows you can follow only those of your identities that they are interested in.
