I ran into the Dean the day before the event. I took a class that he co-taught last fall, so he recognized me and I mentioned that I was going to the Gates talk. He asked me if I had any "hard" questions to ask Bill. He went on to describe a few that he wanted to ask (and did), but explained that he didn't want to make them "too hard." I mentioned the Waterloo C# issue, and he said, "Oh, but that was the Waterloo faculty who initiated the offer, not Microsoft!" I said that's not what I had heard, but then he talked a bit more about what he wanted to say and then had to go, so I didn't get to talk about any of the other questions we had. Ah well; one of the event staff gave him a flyer the next morning (though he didn't incorporate any of it into his own cue cards). In general, the event staff were very friendly and a few said they were glad we were there. Right before we went in, I saw one older woman holding up an anti-Microsoft sign by the Bears Lair entrance across from Zellerbach, but otherwise there was no other dissent that I saw.
Also, I'm proud of Ping for his statement.
So far I've gotten one positive blog post as a result of the event and one negative (and rather irrational and hateful) one, both on other posts since I'm writing this one a day late. Interestingly, the negative one exhibits the same sort of irrationality that I sometimes see liberals say toward conservatives, and one that I don't like coming from either side. It's just as worthless to call Bush stupid as it is to tell me that I and others like me should be "shipped to some deserted island" - both are examples of a personal attack fallacy, and neither change minds or add useful information to a particular argument.
