The good thing about having multiple Mastodon servers is you can sign up for multiple accounts (one on each server) and use each one for a specific purpose. I have three separate Mastodon accounts: one for general postings, one for posting photos only, and one for book reviews. Followers can choose which 'aspect' of me to follow and ignore the rest.

This is unlike Twitter, where followers have no choice but to put up with my thoughts, book reviews and photos even if they are only interested in one thing.
