U have to read the articles surrounding each guitarists ranikng to understand thier reasoning. When i first saw the list I was like kurt doesnt deserve to be number 12 but, when I read there reason I agreed with them . But one thing i didnt like was that they had kurt on the list and no king buzzo from the melvins. The melvins where one of the main fources of influence behind grunge and king buzzo taught cobain how to play guitar. They used to be liek hey krut get lost but, kurt begged him to teach him. One more guy that was real influential and had a big following I didn't see listed was dave navaro. If u ask people who play guitar that grew up listeing to rock in the 80s and 90s what inspired them, to write heavy riffs with solos etc etc it would be Dave Navaro. I didn't see him on the list I could be wrong. Let me check , no hes not on thier iam right.
