Twitch is an extremely imbalanced platform in regard to discoverability. Their model is to 'make the big bigger' and monetize a narrow field of creators well, rather than monetize a larger pool of creators. There are a number of valid criticisms of the platform, but this one is the most painful for new creators to contend with by a wide margin.

It also sucks for advertisers looking to work directly with those creators because it narrows the field of creators large enough to work with. Plus it inflates their viewership with users that may be less suitable for targeting.
