This reminds me of a Tina Fay quote: “It is an impressively arrogant move to conclude that just because you don’t like something, it is empirically not good. I don’t like Chinese food, but I don’t write articles trying to prove it doesn’t exist.” None of the arguments presented are particularly compelling. In particular, I find the paragraph describing why "IMs don't scale" kind of hilarious, as someone who has been on too many email threads where a seemingly endless stream of people are "cc-ed" in. Ultimately, I think every channel has its strengths and weaknesses, and teams need to figure out for themselves what the right mix is for their combination of size/personality/needs.
