Another one from the clean-out my email files. Earlier this year, I was visiting at Yahoo doing briefings. At another Yahoo campus, Cornell University professor Jon Kleinberg was visiting and giving a standing room only lecture. I’d have been standing with everyone as well, had I known. Kleinberg is legendary in the search world, and his work with links attracted attention at the same time Google’s did. I was pleased to meet him personally at the end of the day, when we both ended up at the same restaurant with Yahoos. You can see what the Yahoos got in his lecture here, which leads to a video of his talk on large social networks and how knowledge moves between communities.
