Re: "Tavis wants people to stop using PostScript"
Untrusted, true, fair point, but that's the vast majority of real-world PostScript. Unless you hand-crafted the code yourself then you shouldn't trust it. If that's all you do, then none of the recent security bulletins affect you (congrats, you win!).
Most people, however, just use ImageMagick etc, on PostScript programs they picked up from some random place and don't even realise they are running program code.
