Sorry to the people who will defend free software unquestioningly, but the logos are bad. That emacs logo is just downright ugly. Even the other one, the stylized E in the circle that dkbrk talks about, is very bad. Both look like some high school student messing around in CorelDraw for a couple of days would come up with. The only reason I can see why the people involved in these projects wouldn't get a real designer (meaning: someone who designs for a living) is that they have a lot of technical skills, but very little design understanding. Or they just don't care, knowing that in the end its how good the code is that matters, and don't want to bother. This extends pretty much to the whole universe of Linux software and distros. So it doesn't matter much with Emacs, but it does matter when you want to make a distro that is user friendly.
