Youtube should have a trending part in their profiles like the most popular search words, videos. This will open doors to more business opportunities like marketings and stuff. People might use those data to look for popular words search to make relevant videos that will most likely turn into a hit. Also will understand how a video turn into hit for brands companies marketing can use to make commercials ( like who is searching for their media,(age ,sex) so they will know their target markets and know who they are not reaching and whom they should, if they want to increase their brand's name popularity and relevance.
me personally i think a person can not know nothing,trust me whatever subject it is ,it may be small but they will know something about it,either hear about it from someone and not really understand it but they will know.
