I didn't see a question about this anywhere so I decided to ask it.
I anticipate an answer like "it best represents the site name," which is all right, but I'm sort of looking for an in-depth look at the creation of the logo from, perhaps, the minds of those who created it.
And while we're at it, I'm curious if it is geometrically awesome. And by that I mean, were there separate shapes and such that determined the curve of the overflowing units in the logo? I'd like to know if simple things like those were employed in the creation of the logo.
I ask because it's so recognizable now, like the yellow arches or white "f." It's important to understand that something's icon is much more important than we know in terms of branding on marketing (the people over at Graphic Design probably agree :P).
