Its from this awesome book I am reading right now: What Video Games Have to Teach Us About Learning and Literacy

“In such a network, the other players and various tools like cheat codes are part of what I know (and I am part of what the other players know), even though neither the players nor (at least, initially) the cheat codes are in my mind. My knowledge is not only social, it is distributed outside my body. If you were to assess just my skills playing video games alone in my own home, you would underestimate me. You need to assess me as a node in a network and see how I function as such a node. The knowledge I gain playing games, limited as it is for an old baby-boomer, is but a part of my functioning as such a node, and it is knowledge that can spread into the network as well. In turn, knowledge flows to me, making me better than your original estimate would have assumed.” (p. 189)
