It would be good for free software movement leaving the gnu icon just for the GNU operating system.
They are different concepts at all, since GNU is free software in the same way that some *BSDs or SuperTux are: they all satisfy the free software definition. I know that this distinction has been done very well yet and we have text material for writing a lot of books, but I'm missing a free software image/logo. I don't know if it would be good that FSF represents the free software idea beyond than working for it. At any case, in my opinion, the logo of FSF doesn't meet the purpose of presenting that something is free software (compatible). The main reason is that it is basically letters. I liked a lot the original idea of relaunching the GNU image, but now I think that, instead, it should be better presenting a new free software image. The scope of GNU is limited, our mission is the adoption of free software, which is much more important. As an idea more for the brainstorming, I propose that the free software image/logo be based on a freedom symbol with some of the following elements {computers, bits, pixels, networks}. Human happiness or natural things such as flowers could be the freedom symbol, though. Some final thoughts that could be useful: * Attribution to GNU for every free software piece could be considered unjust. * Gnus are not related with freedom in computing for most of people.
