Google's Moderator service, which up until now has existed as a standalone product, is now available within YouTube and to all its users. Previously, YouTube had integrated it into the service for special events, and given access to a few select users.
The core of the service, which has users voting up or down on user-submitted ideas, began as a pet project of Google engineer Taliver Heath, who built it to help prioritize the barrage of questions asked during Google's company meetings and hosted lecture series. In its transition to YouTube it serves a similar purpose: bringing order to the relative chaos of a few hundred million users chatting about videos--many of which leave such rowdy feedback that the company added a tongue and cheek audio preview system for comments back in 2008.
Though unlike comments, which rest on a video page, the company has put Moderator on channel pages where channel owners can police items that are off-topic or offensive. And like its Google Moderator sibling, the list of ideas can be embedded outside of YouTube. It also has sorting tools to rank ideas by date or popularity--both total votes, and items with a high velocity of voting.
