Yes, very much. It had even a few more really useful tricks like press and hold on a comment and a menu would pop up to let you do different actions, like reply, quote, select text, save the comment or even translate it using google translate. It was really awesome, clean and intuitive.
Karma and votes should stay but be hidden to other users. Karma is a good way to detect bots and trolls, but just admins and moderators should see it to act on them if needed. And up/down votes should be hidden too because of the hive mind phenomenon that it produces (Experienced on Reddit): often, the funny or sassy or apparently clever comment gets upvoted and sometimes, the comment with knowledge about the post gets downvoted because the first joke was funny. Many people may not have an opinion about the issue but upvote the funny guy and downvotes the real answer just following the hive. Hiding it, each person reading must decide by themselves if they upvote or downvote a comment.
Prizes and awards could maybe stay, not sure
