I really want Lemmy to work but I'm having a difficult time tracking different communities across different instances. It feels like I'm doing something wrong. I typically just land on the lemmy.world front page and scroll through there, and I see some interesting stuff, but I'd like to learn how to curate it a bit more
Try this: go into your user settings, change Type from Local to Subscribed and Sort type from Active to Hot (or New if you prefer that).
Then click on Communities on the top bar, switch the list from Local to All, and find communities you're interested in, you can also search for specific names.
Avoid names ending in @beehaw.org if you see them, they defederated us so we can't interact with them anymore.
When you find something you like, click on the community name to go to their page, on the right you'll find the Subscribe button.
After you subscribed to enough communities, close lemmy and open it again, see if it's better that way (it is for me).
Important note is that Hot is current broken in Lemmy leading to older posts getting boosted to the top in error. It's currently being worked on for the next release.
Apparently some idiots from here think it's fun coordinating a troll-attack on them and they don't have enough mod power to deal with it, so they removed their connections with us and sh.itjust.works.
