Can I follow another user even if we don’t share the same spaces?

Yes — following is not limited by shared space membership, it is a user-to-user connection. This means you can follow any member of the community and see more of their activity in your personal feed, even if you never join the same spaces as them. The feature is designed to make it easier to stay updated on specific people’s contributions across the entire community, rather than only inside groups or spaces you are both part of.
