Star channels and people with occasional activity that are important for your day-to-day work (not necessarily all the "team" ones). Create a section at the very top above Starred with the places and people that you need to talk to daily. Customize your alert/sound settings, and right click channels to change each of their notifications and mute status. Better yet, leave the ones that don't matter. Ignore the lower channels when they become bold and look at them once a week when you have the time. If something critical in an unusual spot happens people will DM you so don't worry.
