The Youtube project tool

Today i want to talk about a very special social network to me: Youtube project. Youtube is a website created to share videos and media with all the people around the world, for free.
I started using this network when not much people used it (in may of 2006). I think its a great plataform to approach people to the world events. In youtube you can find thousand of tutorials of anything you want; you can find some of the music you like: live concerts, exclusive publications, and so on... You can find amazing notices of the world wide happening... you can share your opinion with other people to debate contents or anything you like. But... not all is perfect: in 2009-2010 youtube was bought by the google company and then started to be comercializing, censoring the online contents. Now you can't see all the artists and videos.
Anyway youtube is a great plataform, i use it almost everyday, mainly to listen music, because its easier than download it and you can create your own playlists and albums with music. Thats why i like Youtube, and i think it can be a powerfull media to conscientize society... or to make society stupid...
I think that this social network is less invasive than other networks like facebook or twitter, because it doesn't control that much your social relationship.
