Youtube's strength has never been as a portal, but as infrastructure. They tried feeding video bloggers with video responses (though that feature is going away), there are channels, which were always terrible to navigate, and there is of course the cesspool of comments. Youtube grew huge because it was easy to embed stuff and link to and upload with. So what's the high barrier to entry that you're talking about? Vimeo has its creative community and Wistia has great embedding tools, but what other sort of niches do you see popping up that steal power users away from Youtube? What sort of business plans even make sense without Google's infrastructure and deep pockets?
