Medium has brought comments back in a meaningful way through Responses.
We Can Fix This F*cking Mess.

Why this works: Each comment is also its *own article* and can get recommendations, reads, etc. Heck, I even had a publication reach out and ask me if it could include one of my responses to someone’s article as an article in its own right. Of course I said yes — and the experience is encouraging me to write more thoughtful comments throughout Medium. (Not that this is a particularly scintillating example, but still.) By the way: This is also something WordPress could easily support.
