>YouTube is still useful if you know how to dig deep and find content...
I'm working on alternative YouTube recommendations to solve these exact issues. Search a channel you watch to get a list of other channels making similar and related content:
The lists are inter-linked so you can click the icons and "surf" from channel to channel to discover more creators. The algorithm prioritizes smaller channels to help users explore deeper into subject areas.
We've also mapped YouTube by plotting a few thousand YouTube channels in a 2-d mapping with a drag and zoom Google Maps-type interface, placing similar channels closer together. You can get a sense of the entirety of YouTube and how broad subject-areas are inter-related.

(We're getting weird "Please try again in 30 seconds" errors from Google App Engine, but an immediate reload will usually work. Any advice on this would be appreciated.)
