I think most of the answers to your questions can be answered by the question that this comment section is responding to, to understand the framing that I’m commenting in:

What’s different about this time and with Lemmy to make it a feasible alternative to Reddit? Is it random chance?

But, this is the first and last Reddit related thread that I plan on participating in, so I’ll be cheering with you, if we ever get the miracle of reddit evaporating. Although, I would be worried where they would all end up.
