Thing is, as I understand, on kbin, you don’t really get a feed of the people you follow like on mastodon.
There’s no dedicated follow feed, yeah, but I noticed posts and threads of followed accounts showing up in my subscribed feed, even though they were made in a community I’m not subscribed to. So I think the follow and subscribed feeds are probably just merged together currently, or rather “following” a user is being treated as just a flavor synonym for subscribing to a user.
That’s why I use Copilot.
Asked it for the official documentation, got a link to the /current/ documentation’s chapter on operators. Then asked for the heading about the IN operator and it gave me all four of the numbers. No need to wade through outdated or irrelevant results.
