I’m surprised to hear about the slowness issue - I think this is the first time that I have, though I am definitely spoiled at Discuss.Online that has such a great technical admin (he also is the one who was developing Sublinks, before life and a baby intervened:-). Is lemm.ee much faster than lemmy.world for you?
Tbf there is legit fear in the USA that Trump will start to place bans or at least watchlists on social media outlets that Musk does not make money off of. Then again, I thought that LW wasn’t really associated with the USA in any way besides having a bunch of users from it, and anyway you have found a perfect solution to the problem - if they don’t want it, go somewhere else that does allow what you need.:-)
Mods are generally not going to surrender their power, especially as differences in moderation techniques is what most often leads to new community formation in the first place:-).
Other than PieFed’s Categories of Communities, the only other ways I know of to make Topic aggregations like that is to either find and switch to using an app that provides such (I have heard of at least one, but I don’t recall which:-), or else have many Lemmy accounts and constantly switch between them - like one for News, another for Memes, etc. Or you can browse by All, and see mostly only memes and news from the USA all the time:-P.
But PieFed provides numerous methods handle this: not only Categories but also Topics to aid community discovery, and you can trigger Notifications for anything - a person, a comment, post, or even an entire community.
One day very soon I strongly believe that PieFed will surpass Lemmy in terms of usability. It already has in so many ways, though not quite all.
