I would like some kind of way to browse or filter through channels so that I can find new content from smaller creators more easily. Perhaps categories that are better organised and a system in place that does not favor the biggest YouTubers as much as the YouTube SEO currently does.
YouTube is slowly falling victim to the 'rich only get richer and poor only get poorer' concept. The only difference being the bigger YouTubers only get bigger and the smaller YouTubers get squashed away from any exposure whatsoever.
Maybe they could have a Highlight tab for each category and sub-genre that specifically selects the best content to show from YouTubers with less than 100k Subs. Or - to go one step better - a custom highlights tab so that you can get highlights from specific categories and sub-genres with a subscriber count filter (so you can filter the results to only show videos from people with 1k subs or less for example).
I say this because I know a few small YouTubers that have genuinely amazing content - they just can't get it seen due to the reasons stated above.
