I've read some estimates of there being over 2,000 programming languages -- so it's probably fair to say I missed more than one.
I think I got all the major ones, though. If you have a favorite not on the list, just add it below here, and I'll put in the next favorite language survey. I'll also put in in the result summary.
Edit: actually, maybe not.. I see I missed O'Caml. I would have also have liked to have included Arc. There have got to be some Arc fans on HN.
