You Tube Trends is a constantly updated and human-edited website that tells you what is trending (going viral) now.
The You Tube Trends website describes itself this way...
"YouTube Trends, is a destination for daily insight into the zeitgeist of the world's largest video site.
"The idea for YouTube Trends started with our desire to find new ways of identifying the viral and newsworthy content people love to share and packaging it in an easy to digest format. With over 35 hours of video now uploaded to YouTube every minute, we wanted one place to distill the videos people were sharing and discussing with their friends as well as understand what YouTube could teach us about our culture and current events."
