Ever read YouTube video comments? They're not exactly renowned for intellectual debate. Now, the company is taking steps to bring more important and useful comments, instead of words of wisdom from trolls. YouTube will let the channel owner automatically delete comments with certain words.

"There's a lot of room for improvement," said Nundu Janakiram, YouTube product manager, when asked about the current state of comments. "So comments will soon become conversations that matter to you." (Here's his official blog post on the changes.)

You'll start to see a new set of comments rise to the top: those by the video's creator, "popular personalities" (i.e., YouTube celebrities), "engaged discussions" with a long thread, and people you know and interact with — both on YouTube and Google+.

Will this mean less trolls?
