* We have a couple of all-sites channels that a restricted on who can post (in practice or effect for the smaller ones) that are subdivided by function.
* Use threads and switch to threaded conversations fast rather than in channel discussions.
* Keep team "business" and "social" channels separate even if they are effectively the same groups of people.
* If have a support channel, make sure to put what the resolution of the issue/conversation was in a summary comment at the end.
* If you're remote, jump to video/voice conferencing before you get to a 200+ comment thread ...
That's a few for starters.
