To be honest, the only thing that holds me back to delete my reddit profile is the DH subredit. If you can find a way to move away from Reddit that would be great! At least keep up the boycott for sure!
Yes we should, but reddit has been taking them down as spam, A LOT.
I don't know about the sidebar, there's a lot of discussion from mods about that, the threat to remove mods for other reason is probably part of the concern.
Lemmy has a few bugs and it's slow. The subscribe button sometimes take a couple minutes to work, and I can't even create a post in the lemmy.world community. It will take a few more months to perfect it.
