One of the first things I noticed as I skimmed over some of the tweets was that if the discussion had been started with a blog post that detailed all the arguments at the start, some of the back and forth elaboration of points (as well as the bickering and insults) could possibly have been avoided. But of course, that's just me looking at it in hindsight. To Zed, maybe it was just something that he saw and quickly tweeted about, without giving a second thought about what could ensue afterwards.
Also, I think this is on point[1].
