On Browse Stream Page add a section for Hosts below the "live" People You Follow"
At present the only way to know of a host occuring by people you follow is to be in the channel when the host is activated. A good idea, one that would benefit greatly those recieving the hosts, is to place a section below the "People You Follow" on the Browse Steam page. This would show people logging in onto Beam that someone you like to watch is supporting another Streamer with their fan base and exposing them to newer audiences.
id really like to see this on the mobile app. a Hosts section in the following tab for live hosts.
