I personally don't like KBin's UI. It's an immediate turn-off for me. Text too small, vote buttons look weird. Also I just loaded the homepage and the top posts are "🤔🤔🤔", "ich🚗iel", "Every time I leave or enter the house", and a generic meme. No thanks, there's enough trash like that already on the Reddit homepage.

I'm building my own Reddit alternative zsync.xyz. I'll open source it in a week. Hoping to federate it one day and make it into a pcmag article. I def respect the Lemmy dev(s). To an outsider a Reddit clone might look trivial to build but it's actually a ton of work, and of course an enormous chicken & egg problem to overcome to actually get any users.
