Have you encountered that when replying to a comment from your post?
Sometimes, I thought my comment was already published only to find out later it wasn't because it was too short.
I don't know if I like it or not but sometimes it could be frustrating when you need to make your comment longer just to make it reach 60 characters when all I want to comment was something simple and short. Short reply to a comment doesn't always mean it has no sense at all. Its just at that moment, that's all I want or have to reply to someone's comment.
