YouTube will try to clean up its "barely literate" comments section. 

The video-sharing service says it's revamping the comments feed which some users claim is overwhelmed with crude and vulgar postings that usually don't have anything to do with the video. 

A YouTube blog post outlining some of the changes says people who share their videos will have new tools to filter out rude, racist, homophobic or irrelevant comments. The options will allow users to review posts before they appear, block certain words and phrases, and save time by auto-approving comments from friends. 

The changes are rolling out this week.
