"No Reply" bug
As you can see in the screenshot (http://imgur.com/KnaH8GA) there is no reply button. I refreshed the page and nothing happened.
Here is the link: http://www.duolingo.com/comment/509926
I have that in every single comment! I literally can't reply to any comments!!
I can't reply to any comments either, not even individual ones. I wanted to give some people advice on Russian but I can't reply to their comments.
Found a workaround with css, lol :D But I cannot see the reply button itself in the markup anyways. Duo devs should really fix that bug. Or, if it's intended, put some message explaining why you are not allowed to reply
