I think kbin's thumbnailer could use some work.

You're right. I'm the one who's confused because I'm not used to where to look in the kbin UI to see where a post came from.

You are posting from beehaw and this post is about kbin.social, a different server running different (but interoperable) software.

It hasn't been that since it got self-posts and comments in 2006; it's a forum.

Lemmy and kbin are also forum software and should embrace being good at that.
