Memory is so weird... I feel like I saw it in person. But given that the site was started in 2008, and some other details I remember about the talk would indicate that I must have heard it at least a year after it launched, I can't figure out a venue where I would have seen it in person -- the most likely venue being a talk at uni, and I was long out of university at that point.
Why at least a year after? I also remember the speaker relating a conversation he had with someone from whom it seems like he was asking for money: maybe a VC? The VC told the speaker, "I sat on a plane next to somebody who told me he doesn't answer anything on stackoverflow any more because all the questions are answered too quickly." And the speaker responded, "So wait. You talked to a random person on a plane. This person had heard of my website. And his main complaint was that questions were answered too quickly?"
Wikipedia says SO did get VC funding in 2010, so that sort of matches; and quote from sibling comment is along the same lines. So I don't think I'm imagining things, but I also don't think I'm going to be able to give much more information. :-)
