YouTube comments are on the verge of being a ridiculous mess.
The new commenting system and Google+ integration is hard to follow and moderate. Comments no longer appear in users’ inboxes, which is where many people managed them.
So how can you regain control of the comments on your YouTube videos?
YouTube has added a comments management page (http://youtube.com/comments). This page lists all comments. You can respond to, remove, flag, thumbs up, or go straight to the video from this page.
At this point, oddly, you can’t directly reply to comments from the management page. However, YouTube says you will soon have the ability to reply directly and expand replies.
