I heard that the All feed aggregates content from all communities that instance members have subscribed to, meaning if I subscribe to a new community, it’ll start showing up in everyone else’s All feed.
Let’s suppose I have an account on an instance with a particular thematic focus. Should I avoid subscribing to communities outside of that theme, in order to preserve the purity of their All feed?
Not quite, the All feed shows you all posts from all communities subscribed to on your instance. If there isn’t a user subscribed, it isn’t pushed to that instance.
Oh! That’s interesting. Thanks for clearing that up. :)
