Start here. Notice the cultural differences. Or you can use it to pick apart our argument.

I have no horse in this race (pun very much intended), but after reading this article and the one linked to below I... still don't see that much of a difference? I mean, apart from a handful of wacky quirks and a very distinct visual style (which I love, don't get me wrong). They look fun, but I could easily see individual or whole groups of D&D goblins possessing some or even all of these quirks and still being recognizable as a D&D goblin.
I mean, there's more difference between traditional D&D goblins and Eberron goblins then there appears to be, at least from these two articles, between traditional D&D goblins and PF goblins.
