Does it matter that it's powered by Node.js? I mean, tech can change. We need an alternative to YouTube, and that's more important.
I'm trying to understand what an alternative to YouTube is going to provide the average end user. What company is going to put up the money for something that will never make a buck, at that scale? A YouTubeToo will inevitably be the same thing. Just like every new photo sharing site inevitably goes down the same path, because you can't just make shit free and expect to survive.
Not particularly but it's just cool to let people know what's under the hood. Node.JS can power a lot of powerful APIs and is itself quite a powerful piece of software, I think it's cool to let people know it's a Node app as opposed to something written in PHP or something. If you have a better tagline though let me know ;)
