We have just announced our plan to build an alternative to YouTube: Framatube.
Instead of hosting another centralized video-hoting service, we have choosed to fund and help @Chocobozzz the developer of the Free-Libre software PeerTube.
PeerTube generalizes video-hosting by creating a network of federated hosters, whose videos are shared in real time between viewers.
You must have lots of questions, and we’ll be happy to answer them! Don’t hesitate to ask them here, and to add a to the question you were wondering and that someone already asked for you ;).
