I agree completely. We really need to make onboarding to the fediverse as painless as possible. If there's a barrier to entry the general audience will gravitate towards tech savvy folks. That's cool and all but what made Twitter and Reddit so good was the diversity of voices.
There were tech folks but also senior citizens, people who don't usually use social networks and those with marginalized voices. Both platforms started with mostly tech folks, Twitter didn't really blow up until the color revolutions, reddit really came into its own after the digg exodus.
The fediverse is making big gains because of both platforms thoroughly shitting the bed but we're not the only game in town. Threads has an extremely low barrier to entry but it's an entry into a Max Headroom style blipvert hellscape. Making our barrier to entry as low as possible could really help us "rescue" those users.
