I cannot put into words how profoundly stupid this "feature" is. AOL and Geocities pages were genuinely more user friendly. Whoever added it, refreshed the page and said "yeah, this works well" and left it in should be fired! ...out of a cannon and into the Sun!
I've tried Mlem and Memmy and both seem to have a single fixed "Hot" feed that has not updated since the last time the apps updated. It's still showing me some startrek post from two days ago, as well as a bunch of posts from beehaw despite it being defederated. Active sorting has this problem of constantly shifting. Going to specific communities and sorting by "Hot" there seems to be the most tolerable way to browse, but only Memmy can even do that. It's rough but hopefully these things will get pretty good pretty fast. I wish kbin had an app but for now the webUI is actually pretty usable.
Lemmy.world sounds least political but it's not stable. Apparently beehaw is now also defederated from .world so immediately we're missing some huge communities that are now going to be split across two instances that don't work together.
So now I'll need multiple accounts to use multiple instances of the same thing. This sort of defeats the whole purpose of a connected system. It could just as wel create worse echo chambers than we have on traditional socia media.
Beehaw defederating from the biggest instances is why I ultimately made an account over here but it's honestly not a good sign that the fediverse is already imploding. Most of us left reddit to get away from idiots on a power-trip trying to control how we talk to each other and it took about eleven seconds for it to get just as bad over here.
You should be able to do it pretty easily. There are docker images for ARM64 in Lemmy docker repository so you can run it on pi4. If you have older pi, you'll probably have to build it from source though.
