I guess I didn't think about it enough, but if someone emailed in with a feature request, or with an opinion that this tab should behave differently or whatever, I thought giving explanation would be helpful. "I actually tried it that way, but it didn't work because X, and Y, and I didn't even think about Z which breaks the whole concept, etc etc." As a dev, these types of explanations would seem meaningful to me. But in reality, these conversations are mostly not helpful for either party. That was the point I was trying to make in the post.
Fair point on 2, I honestly didn't expect anyone to read this tonight and had another post planned I thought might get comments on HN, but I just put this up for now until I could finish that one. I will do better at giving context next time.
