Honest to gods, this conversation happened today, and it may have cost me a job opportunity. The customer was super impressed with my menu design and animation, and wanted to know who we got it from. When I said I did it, their face lit up! Too bad as soon as i said GIMP, they weren't interested anymore. Has anyone else experienced this? What do you say in similar situations?
Using the long name (it's actually GNU Image Manipulation Program) is a good idea, but I have never actually had anyone press for the actual name Not giving the name also means I don't have to explain anything if I later used Inkscape or something else as those would also more or less fit the description I gave.
