At long last, a tech company has promised to tackle head on a problem it created. Google says it is making tweaks to the commenting on YouTube. The comment threads on the video sharing site have long been considered the seedy underbelly of self expression online. The company's proposed solution is three-pronged. YouTube will allow the person who posted a video more control over the comments section. It will also leverage Google's massive data powers to give people browsing a custom view.
