Dave, I wanted to tell you that I think the way you were handling the situation with DHH on Twitter was great! I saw a video on YouTube titled "the last lecture" a while back, and the biggest takeaway for me was how the guy defined an apology:

Proper apologies have three parts: 1) What I did was wrong. 2) I’m sorry that I hurt you. 3) How do I make it better? It’s the third part that people tend to forget…. Apologize when you screw up and focus on other people, not on yourself.

This has stuck with me and I noticed you were following on it very well, patiently and with humbleness.
