A problem many have realized is that there are many /tech, /gaming etc. communities in different instances/servers. There is already [https://fediverse.observer/](https://fediverse.observer/) , so I think it wouldn't be too hard to make a service that periodically roams the fediverse, checks for example the last 100,000 submissions of each (or top 100 active servers or something) server/instance, and gets info on all the communities/subs involved. Users could search communities, and if they write "gaming" they would get a list of all the active /gaming communities and info about them: subscriping users, total submissions, instance location (geographical) etc. This could be used to find suitable /gaming communities for your needs. A desireable future feature for both kbin and Lemmy would be to find and subscribe to multiple communities with the same name from the fediverse, and manage them to a single feed if the user so desires. Ideas, thoughts?
