The quiz made no claims to be exclusive, inclusive, or even representative of anything. It was simply "name the guitarist." No one is missing. No one was slighted.
Weezer and Oasis are on the same page as Pete Townshend, George Harrison, Jimmy Page, Brian May and Eric Clapton? That's the first time that's ever happened.
But how many people with Jet Punk accounts have worked a few offices down from the brother of one the people on the list? I bet I'm on the very short list. Never made the connection even though he had the same last name until Metallica was playing the next day and our boss said something to the effect of "Kent is taking tomorrow off since his brother is going to be in town and he doesn't get to see him much when he's on tour." Never talked about music with him, he liked talking about college football a lot more.
