Issue isn't so much the viewer / interface. Easy enough to adapt or as others have mentioned looks like there is a flood of options coming. The real issue is content. Lemmy is a vertible desert. Most posts on Lemmy are about Lemmy. We need sub migration or this bombs. Instead of reddit mods posting pictures of John Oliver and telling themselves they are revolutionaries, they need to pack the hell up and encourage user base to move here. Can you imagine the smug grin on Spez's face when people are channeling their creative energy to post hand painted John Oliver artwork and Spez memes to his servers? He could give two shits if all of reddit was AI Spez nudes if traffic is up. Leaving and NOT CRAWLING BACK is the only thing truly impactful. If you're reading this you are least starting to solve the problem.
I switched to Liftoff after Jerboa had issues working on lemmy.world for a bit. Loving Liftoff! Little difficult to find in the app store, so search by name.
