Is anyone aware of Mastodon instances that are solo, but with bot accounts just for the solo host account?

I’m thinking about something like A Dave Instance with a local timeline with posting bots for various nuggets, for example, bots with regular posts of:

- My reading list backlog
- Fun small coding ideas I’ve written down
- Healthy reminders (go take a walk)

Pardon the tag @gordon but I think I’m riffing a bit on your line of thinking here
