I think kbin is pretty nice as it is and I am sure the developers will make it even better in the future.
A really nice bonus is the lack of advertisements on the platform (or maybe I am blocking it, I dont know?). compared to official reddit it feels very refreshing to only have content to focus on.
This is a great start. I think a first goal should not be to replace big tech, but the create thriving alternatives. You should not have to feel that you are missing out by not using facebook, twitter, instagram, reddit etc. And with Mastodon/Lemmy/kbin we are getting there even if it is very very early still.
