To be fair, there was a viable and easy to use alternative (Reddit). And the community was largely tech savvy.
Today there are more computer users, so the average tech literacy is higher, but the tech literacy of the average computer user is lower. People want slick, easy to use, centralised solutions.
I’m not too concerned about this though. I think realistically the fediverse could achieve a critical mass to keep it going, but won’t be too large that it becomes just a bunch of noise (like Reddit).
I agree it needs to be more intuitive, however, I would argue that Linux is far more intuitive than it used to be. Still, people didn’t switch.
Another driving force is that people don’t like change, and people use whatever others use. TikTok bought another company just to get their userbase, it’s that important.
The fediverse is fighting an uphill battle. You’d have to provide a platform that is far more intuitive and engaging than the competition, while relying on volunteer labour.
