If you look at the most popular streamers over time in any given niche, a huge fraction of them are cut from the same cloth as shock jocks like Howard Stern.

There are other strategies that work (banter with 2+ people, very attractive person showing off how attractive they are, actually informative videos, etc.), but the modern version of Howard Stern tends to dominate these when someone does it well (as in, gives people what they want) in way that doesn't seem to be true for writing.
