Read this for the sidebar management tips alone! Wow, I had no idea how cluttered my sidebar was until I followed Peter's guidance from this post.
Declutter your sidebar by hiding all channels that don’t contain unread messages and are not starred. You still won’t miss anything, as they pop up if there’s chatter, and you can always use ⌘-T to open the Jump menu. It’s amazing how much better it feels if there aren’t 50 channels you need to scroll through all the time.
