Hey, I'm working on a project to help users discover more interesting content on YouTube. Our channel-based recommendations allow you to search a channel and get a list of other channels making similar content, with a focus on surfacing relevant smaller and more obscure channels.

We have most of these channels mapped and I think you'll be able to discover some interesting new content on some of these lists, especially in the more niche categories of the shoe commentators and the London transport channel:

I'd recommend clicking through to Trenton & Heath's list for a more complete listing of shoe channels:

I hope some people find the tool useful. You can search channel names in the top bar or click icons in the lists to navigate to different channels' pages.

Cheers!
