Its different for me, I have NEVER seen an actual Slipknot fanboy, only hear people talk about them and how annoying they are... Guess I'm lucky.
But as far as their total album work goes I doubt I could listen to everything they've done, but they've made some kickass stuff which makes me understand why they're so known.
As with a lot of idiotic fans, (metal fans being some of the worst) they give bands a bad rep.
