Really? Did you really have to say it that way? I use the Gimp every day, and it's quite good in my opinion. It does what I tell it to, and not what I "mean". Photoshop does what you "mean", as defined by Adobe. As an example why that's wrong, something like "I'll interpolate this scaled bitmap linearly, thanks" is frequently the wrong solution, but happens anyway when you scale a section of an image.
Now I know this article isn't about the Gimp, but when someone wants to spark a flamewar by claiming the user interface to the Gimp causes him "to go blind", it really discredits his other claims nearly instantly.
