Or even more not so extreme examples, for examples let's say your music player would be called "Brown Juice" or something like that, would you be happy about that application, vs for example "iTunes" or "Soundamp" or whatever.
You know these are extreme examples but just show you that the power of words is very clear in what kind of images they create in our thinking, I bet if Gimp would change their software name to something like "GNU PhotoEdit" or something like that, more people would be willing unconsciously to work and improve it also vs working on this "Gimp" that still uses that silly logo with the Gnome Mascot. It's very unprofessional and you wont attract the best designers or developers if you don't think about the big picture.
That's just my view on the thing. The package and nice colors matter, but of course the interiors and working of the software is that matters more, and on that frontend Gimp just doesn't cut it. What I'm trying to say is that maybe they could make the software better by changing it's name and design.
I mean, no professional uses Gimp for photo editing, at least I don't know anyone besides some hobbyist who rarely use photo editing, they might use Gimp. Or am I wrong ?
