I wonder if it would be worth it to have an option to combine content of communities with the same name from different federations into one feed automatically.
Part of those options could be to exclude a community from a certain federation from that feed if their content in that community does not match the others (r/superbowl for instance, where the name does not match the expected content)
What about something like Komet? Then it would still be space themed, but have the K from kbin as well.
