Kbin, it’s an indepedant fediverse project which as lemmy aims at having a similar look and feel as reddit/digg/slashdot.

There is a few differences like kbin has a micro-blogging function, and some right-wingers are not comfortable with lemmy funder being openly communists, but it’s 90% the same at the point you could just treat a kbin instance like a lemmy instance.

I believe that pixelfed consider adding a thread function, but no idea what’s the status there
