They're good ..
The reason Twitch is beginning to lose to Youtube and other such companies is its weakness that it relies too much on streamers.
For example: How fun it's to watch the streamer? How committed he is? How long will he be using Twitch? What happens every time something dangerous happens to someone while having Twitch as an indirect party of how it happened.
Furthermore, Twitch only have guidelines, not rules (or systematic control), and thus streamers have to moderate their streams "alone", and that's very bad for a website, because it's as if they (streamers) are at a restaurant and they order and cook the food by themselves, which causes new streamers really tough to have a footprint in the website.
