I think you can take it up a level from the individual to culture to see it even more clearly. I think one of the most glaring examples of tacit knowledge is simply physical agglomeration. If tacit knowledge wasn't that important, why is it that people pay thousands of dollars of rent just to be in the right spot while 'everything is available' on the net? Why does half of all VC money go into a bunch of zipcodes? Why do so few key professionals network like we're in 15th century Venice?

Physicality and proximity are incredibly important, ironically maybe more so in the world of 'knowledge work' than when it comes to physical activity. An incredible amount of knowledge work happens implicitly when people organize spontaneously without them even being aware. Alex Pentland wrote an interesting book on it called Social Physics where he tried to empirically measure how much more effective in-person exchange of information is.
