Actually, that site is a little below philosophical views: it employs illogical arguments to proselytize in a way that is closely reminiscent of what a wacky cult would do. I would say it gives atheists a bad name, but I don't think the difference in opinion should be polarized as if both groups were out recruiting: for once, I feel no need to persuade anybody my views on God are correct. As for your opinion of agnosticism, I'm afraid it suffers from a common misconception: of course God either exists or it doesn't. Me making up my mind won't change this. My stance is merely that science won't get me to the answer yes or no, and I personally do not feel any faith. It's an interesting topic to discuss, and I concede that all sorts of horribly superstitious fundamentalism are the home of some imbeciles who happen to be believers. But I'm not feeling guilty for what you probably see as "not taking sides", because the only divide I reckon I see lying around is the one separating the smart and intellectually curious from the fruitcakes. And I'm not going to repeat whom I think the author of godisimaginary.com belongs to.
