I am currently using Lemmy.zip through the app voyager.
I can also see content from other places like hexbear and fedinsfw.
If I login to lemmy.zip on a desktop I can use my voyager credentials. But I am only able to view lemmy.world and nothing else here.
If I login to fedinsfw on desktop I can seemingly access a multitude of places such as I can on voyager, including lemmy.zip.
I’m sorry if this is such a dumb thing to get confused about. I’ve heard explanation for what all this is, but I’m still just not quite sure I understand.
I think I’m understanding it a bit better, but in a very broad kind of way.
It can be quite a lot to wrap the head around, yeah.
Imo, it’d be better to stick to using whichever instance you picked, and maybe using another instance, preferably with another software, to see what’s about. Mastodon is what I’d suggest for minimal overlap with Lemmy. Later, you could check something like Mbin, Friendica or PieFed for a reason you may notice as you rotate between Lemmy and Mastodon.
