With the popularity of Reddit and how simple (in theory) of a concept it is, it blows my mind that there is not an alternative. Kbin and Lemmy are okay, but they are pretty big compromise so far.
I can forgive the issues with Kbin and Lemmy because Reddit has had more time and resources to build the platform. My hope is that with the new attention and the open source nature that Lemmy will show consistent improvement to where I don't feel like I'm compromising.
For being an early beta, kbin is usable and remarkably polished. I think the downsides for most people are deciding what server to join and content discovery.
There's been little demand. Give it some time. Enjoy being in in the ground floor, or wait until it's a little more mature. The more use and demand the more we're going to see improvements and alternative mobile apps and such.
Because there isn't enough resources to develop it without any real interest. Most of fediverse projects start as personal projects and evolve as they gain traction.
This version is the worst it will ever be. It can only improve from here as corporate greed is not a factor with open source project.
