I think kbin is more promising than lemmy. The admin seems a good guy, kind and levelheaded. Since a month ago, before the blackout, he build kbin by himself and since then someone even volunteered to help him polishing the site.
The site looks polished but still in beta and they're actively ironing out hundreds bugs and feature request by us users.
Ultimately also the users are nice people. Many of us have donated money and right now the admin have enough money for nearly a year. Source: https://kbin.social/m/kbinMeta/t/177112/kbin-project-management-costs-financing-future-plans
