How about SNSOG – SNSOG Not Son Of GNU?

That would be Sinsog; unlike FOSS, we’re not prejudiced against verbs around here. (What with verbs being actions, a concept utterly alien to the FOSS world.)

Yes, I rather like Sinsog…

Good one. I can’t stand acronyms, recursive or not, which miss initials of what it’s supposed to … erm … acronymize?

Is it a bird? Is it a Plane? It’s the GNU/cronymizer!
