And some times, having the initiative to create such more specific communities could be a change factor for the growth of a social media. Also, with federation, not just the person can choose where to create the community on while not making it a walled garden as other sites would still have access to it, but also if a community for the given subject already exists but the user thinks he can do better, he/she can more easily do it with how expansive the “fediverse” is.
Maybe in some cases, it helps to use Alt F10, or, since I’m using Mint and it may change in other systems, maybe the equivalent for yours?
