Oh my god this sounds just like mastodon. Having a social media site dependent on a manual to use and understand just sounds like the worst idea.
I just love it when people at HN complain about a freaking web site being too difficult to use. Quite some hackers we are! Took me less than an hour to register and get comfortable with Lemmy.
Do you really not see the problem? For Lemmy to face any hope of becoming mainstream your statement should be "less than 5 minutes".
Maybe that barrier to entry is a pro to you, and that's fair, but surely you understand the criticism that a social network should be usable without reading a guide, yes?
