Share idea: YouTube search-pain pill

I finally was able to define the pain with YouTube I've been facing all the time. Say, I wanted to watch some "piano jazz" music on YouTube, but simply searching by these keywords only gives me videos that have them in their title - which is really wrong. Because Oscar Peterson would definitely match, but most of his videos wouldn't be found like that. Tags would partially solve the issue, but hey: I never noticed it before - I can't see any tags on YouTube, where are they? (probably there are tags there, but I couldn't find them). Also, I would probably want to be subscribed to the channel I like, but what channels are on YouTube? It's basically a single user's video blog. Wouldn't it be nice to have a multiuser blog dedicated to "piano jazz"?

So here's a 3 steps idea:

1. Implement a search for channels on YouTube, indexing their descriptions. 2. Implement tags for YouTube and search for them. 3. Create a multiuser blog platform for videos from YouTube (and, of course, search in those blogs as well).

Since the idea is about 1 hour old I don't know how one can make money on it. I also don't know if it's worth trying to implement it (too heavy?). What do you think about it? See any value in it?
