Miro is designed to eliminate gatekeepers. Viewers can connect to any video provider that they want. This frees creators to use the video hosting setup that works best for them - whether they choose to self-publish or use a service. It's the kind of openness that the internet allows and that we should all demand. [...]
Our goal isn't to dominate online video - our goal is to push the industry towards openness.
The project is based on three principles of openness: Open Access (not the meaning of scientific publishing), Open Standards and Open Source.
The Miro Guide contains already a lot of interesting channels!
In short: Rocks!
