GIMP Resynth vs. Photoshop Content Aware
aylons writes "Just after Adobe released videos showing off the content-aware feature of Photoshop CS5, the GIMP community answered by showing the resynthesizer plugin, which has been available for some time and can do a similar job. However, are they really comparable? (In original Portuguese, but really, the images are pretty much self-explaining.) Compare them side by side removing the same objects from different kinds of images. Results do vary, but the most interesting part may be seeing the different results and trying to understand the logic of each algorithm."
I think the main problem most "pseudo-professionals" have with GIMP is familiarity. I myself use OpenOffice.org regularly and the transition from Microsoft Office was extremely simple - download it and start using it. The same is not true of GIMP since it's UI is so different than Photoshops. These "pseudo-professionals", almost certainly have a long history with Photoshop, so understand how to do things using it's UI, but likely don't even know where to start with GIMP and write it off as useless. It is closed minded, but certainly understandable on a professional/semi-professional level. Blender seems to suffer the same problem, since it's UI is vastly different than any other 3D program I've tried (although since there are more available than in the photo-editing world no one program has a "monopoly" on the UI so it's not quite as bed).
Most FOSS doesn't tend to have this problem because it either does a specific task that has no industry standard UI, Emulates the industry standard UI (like OpenOffice.org) or is so simple that it makes little difference how the UI is designed as long as it works (things like 7-zip for example - its function is to open and create archives. You don't have 100s of filters and tools to use so everything can be put into a couple of menus and not be confusing).
