I understand where you’re coming from, but the point for me is that these video hosts already exist - this isn’t just theoretical. The sites are there, buffer time or not. People could easily start using them more, it’s only momentum that keeps it where it is. YouTube caught on because DoubleClick has consistently ranked their own video services higher than ones on other sites. I think that’s probably something that needs to be addressed - if the Google search page for Video was relabeled YouTube, and a second video tab was created that showed video only on non-DoubleClick owned sites, that would be minimally acceptable. I’d also like to see Bing and other engines using its results being better at showing non-YouTube content.
