We should all stop using Youtube en-mass. Host your videos on your own website running on a VPS or dedicated server. There needs to be some way to reverse the effect of the network effect that Youtube has. That way we can decentralize the web again.
There should be some kind of peer-to-peer link sharing protocol. For example, you watch a video about bitshares on say d-tube.com and then you get links to videos on distinct sites but of the same subject.
Alternatives are better to have for ppl to move over. People won't get to hosting things on their own with bandwidth limitations and costs ;) Yup related videos is a good way to keep people looking at more videos on a platform. I don't think dtube does that yet, they just show other videos from the poster...
