I'm pretty satisfied with the new changes to comments/replies (reactions, KLIPY integration, popup writing editor, etc...) that have so far only been on homepage and profile comments. I am now beginning to roll these changes out to all of the other comment/reply areas on the web site. I just deployed these changes to blog post comments, so you can use the new features there now. Be on the lookout for these features to come to the other comment types in the near future.
