Just of top of your head, can you list three reasons they want to join the Fediverse for a “normal” Reddit user?

I agree, there is no reason for most of them to. Why leave a place full of conversation to join somewhere where there is hardly any?

That said, many people want to to abandon traditional social media sites like Twitter/X and Facebook - Bluesky has been a huge beneficiary.

If it did things differently, there is every reason to think the fediverse could benefit from that transition. This trend of turning against the old social media , especially as it has aligned itself with the far right, is only going to accelerate.
