Everyone seems scared but I would be happy that such a FOSS designed project would finally be used in mass scale.

Sure content would not be the same, but the structure of lemmy would probably encourage more discussion and problem solving rather than hate induced comments or crazy mob-like behaviour.

When I talk about structure, I talk about some feature like having a downvote, not so much advertisement, the fediverse, no(or just not so much) incentive to make money from the platform, text based posts, custom front ends, etc…
