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?
I think it’s a good idea to be cognizant about visiting other communities that are not in your home instance. Most people enjoy seeing new things and ideas within reason. I would say that as long as you aren’t embarrassed by announcing to the community your own personal interests then go for it. And if it is something you would be embarrassed to share then maybe make an alt account on that instance for your own personal use.
