To encourage more YouTube users to put their time watching videos to good use, Waves for Water, a non-profit organization, has created annotations that can be added to any YouTube video. The hope is that enough people will use them to spread the word that so many people in this world still do not have access to clean, fresh water.
Waves for Water does a great job with taking something that can be seen as more of an annoyance, and puts this tool to good use. Now the question is how many people will add these annotations (it's really not that hard), to their videos. The more viral the video, the more chance of viewers taking the message to heart and acting.
