description: I’m being blocked from McKinsey’s website as a competitor, a practice dubbed "knowledge unsharing." Although I’m on the receiving end of their access restrictions, the move has surprisingly had zero impact on my life or productivity so far.

An interesting thread on Andersja's about how [McKinsey is blocking competitors from its site](http://www.jacobsen.no/anders/blog/archives/2002/11/08/knowledge_unsharing_on_the_internet_reversed_extranets.html). I'm at the receiving end of it. And so far, it hasn't affected my life in any way.
