I read his blog, and his Viridian list, bought his new book Shaping Things and had no idea such an event was forthcoming. I was not surprised that he would want privacy for such an event, I myself was quite private about my own wedding last year up until a month or so before.
I was surprised because my understanding was that Bruce was married with children, and there is google-able evidence that he was married to Nancy Sterling, the mother of his two children. I know he and she and their kids shared a big home in Austin at which they threw big parties.
It’s interesting to maybe the folks who follow these things.
