I have no idea. I do a lot of searching, some computer assisted, some directed by Bayesian filters, some directed by keyword search, and some just clicking around. I spend about 2 hours a day on searching about math, teaching, hacking, programming, physics, enrichment, and similar. I also employ programmers, and am interested in the problems of interviewing. I guess in that 2 hours I view about 700 or 800 pages, most for just a couple of seconds. I then save around 20 that my systems have marked as potentially interesting. I found it in the bundle.
