I would prefer if only those who wants to leave reddit left. That this would be an option only for those who are prepared to migrate, and not the redditor who likes their new UI and their official app. I think this place might be the wrong place for them. At this point Lemmy gives me the feeling of a web forum, which in all fairness is pretty cool tech wise (I really like the federated part) but also more or less just a web forum. I can't imagine what kind of negative experience the average redditor would have here..
"It doesn't look like reddit" "What are communities?" "Where are all the people?" Etcetera.
Which is fair, I think Fediverse has a bit of growing to do still. That being said, I can live without that kind of content here, and I'd rather have more quality over quantity here. That's just me though, I'm looking forward to seeing where this place ends up.
