In the introduction note, Bill says:<p>"I take a lot of notes, and often share them and my own thoughts on the subject with others through email"<p>Besides email (which isn't that great if you don't have GMail style threads), I wonder whether he and other prominent personalities use a closed discussion forum to engage in discourse about interesting topics like HN does. I can understand why he would be hesitant to comment on a public forum like HN.<p>That said, it's great to see people like PG, DHH (and others) mix with the no-names (or future-names) on HN.
