use 5 circles (0 - quiet, ! - calm, !! - normal, !!! - loud, ♩ - notify) and adjust the 5 loudness settings to these 5 circles and set all other circles to quiet. now sort everyone into the !! - normal circle by default and watch your stream. if someone is too active in your stream, just move him into the ! - calm circle. when you want to read more from someone, move him to a louder circle.
use these 5 circles to control your stream. other circles like "family", "freinds", etc. are just used for sharing from now on.
