The whole idea of dozens of channels is just dysfunctional to begin with. OPs case of 1000+ is the worst I heard of. Chat channels usually only have two types of contents; Announcements important enough to be sent to everyone or questions of the kind like “does anyone know how to…”. Some times you also find technical decisions although such usually happen outside the channels in other meetings. Channels are then narrowed down into specialist areas. What I often see is that channels are only grouped by area and not by content type, so in order to catch important announcements, one must also wade through all the questions and other unrelated topics, in all the channels, to feel comfortable you are not missing out on something. At the same time helping people out on the way is very rewarding and addictive but easily consumes all your time.
