  • Great presentation material Mihai. Thanks for sharing this as it definitely brought back some Internet memories over the last 15 years. I especially like how you laid out the history and distilled concepts like Pagerank to their essence. It's amazing that in the time since you developed this talk that the number of factors that determine page rank has now gone beyond 200 from what I understand!
