In reply to Munyard.

Mostly I really have one main account (my own website) and I syndicate out things from there. Here's a longer post with more detail: https://boffosocko.com/2016/10/17/how-many-social-media-related-accounts-can-one-person-have-on-the-web/

I suspect some of the ones you originally linked to on microblog were actually "shadow" accounts that the service made for different people to subscribe to on their platform, but it's still an apt question. I'm pretty sure that the @boffosocko.com is one of those, and I don't have any control over what appears there or why to my knowledge. The mastodon one is just a mirror of my sites content which appears on Mastodon and that's a common pattern as MB allows users to subscribe to/follow sites outside of it on their platform.

Here's a fun one: "In 2021, the average 18 to 34-year-old runs 8.4 profiles on social media."

Sorry I missed your comment before, but better late than never... Hopefully this manages to find you where you are now.
