I am not very familiar with the technical workings of lemmy, so if this is a really shitty idea, just tell me.

I joined lemmy a week ago and it kind of bothered me that there is not THE me_irl or not THE programming_humor. Would it be possible to add the functionality to link communities together. In my naive opinion, this would solve my "problem" and add the opportunity to not only federate reddit, but to also federate single communities on lemmy.

What would be the pros and cons of such an approach? Looking forward for your comments!
