with #reddit exodus, people should know these numbers :
#lemmy : 141 developpers/contributors and written in mainstream 'rust' language
https://github.com/LemmyNet/lemmy
#kbin : no contributors, written in PHP ( not the most popular language)
https://github.com/ernestwisniewski/kbin
I don't know why there is so much 'hype' on #kbin
I think the lemmy developper have made an error and should not mix coding and politics, but in terms of developement, lemmy has a better structure
