The thread holds no weight in the corridors of power in Goodison and yes it isn't an ideal poll because it offers no middle ground (black and white).Yep. Would prove that polls on an internet forum mean nothing.
Nor is it infallible to knee-jerk votes from fans as you mention. However, that's what part of being a fan is: emotion mixed with rational thought.
That's what we love about football... Everyone has their own opinion and they're welcome to air them regardless of how ludicrous they may be.
Yet on another note, while it will individually make very little to no difference it is a sample of the opinions current fans hold about Martinez.
67% of fans saying they want Martinez out is quite a high number - thus it shouldn't be simply disregarded as emotional nonsense.
Personally, I think if you spoke to a hundred fans coming out of Goodison after a match then you'd find a similar number would say the same.
