I think that if we want new folks, it would make a big difference is we organized the equivalent of a new member drive.
Currently, look at a default front page for your home instance and ask how enticing it is to a total newbie. There might be some good stuff, but it’s foreign and overwhelming. You feel out of place.
Now imagine if the first Friday of January had been “new subscriber day”. People on Reddit and Bluesky are taking about the fediverse and if it’s any good. And on Lemmy there’s a bunch of posts about finding the best instances and memes about being new on Lemmy. That’s a much more inviting beginner experience, and it makes it more likely for folks to come back the next day.
I really think planning for bursts of new folks is the way to welcome people.
Personally, I do want a common communication platform for people I despise because I want to be able to keep tabs on their public announcements. Also, I don’t want any tech platform to have sole authority over who can communicate, as in the present, that will invariably work against the left more than the right.
I do not want to share close proximity to them on a network graph, or regularly engage with their supporters, though. So I agree that federation is crucial. But to be clear, it’s not because I want to ban them from a platform, it’s because I want managed distance and better moderation.
I don’t mind Bluesky verifying them, but I’m glad that on Mastodon I don’t have to share the same giant server as them.
