As some of the guys have said, this list seems a little disrespectful for Guitar World. Regardless of the guitar player or skill, I'm sure nobody would appreciate having their work referenced as tacky, or lazy, or unskilled. Especially when the magazine had previously supported their work. Then again, GW basically gave up any respect in the guitar media when they became focused on covering entire bands (like Limp Bizkit, RHCP, etc) -that is, more like Rolling Stone or People...
But, it's just a list that is used to generate or magazine sales or hype. I have to admit, the comments are funny.
