The world is bigger than professional graphics
IT, graphics, etc. professionals always seem to forget that the world is MUCH bigger than your numbers. Translation: there are a lot of people out there using graphics and other software that are not "professionals" in your narrow sense. I am an instructional designer and I use both Inkscape and GIMP extensively in my work - most of it is pretty basic but no less essential. So what if Inkscape doesn't have all the (mostly unused) features of photoshop? Know whut I'm sayin?
