WebObjects, dead? Can you please define "dead"? WebObjects powers the iTunes store. I think it is doing just fine generating billions of dollars/year for Apple.
I think I can safely say that I know more about the usage of WebObjects within Apple than (probably) every other poster here, and my knowledge in this area leads to me to one inescapable conclusion: it's a dead technology.
HINT: My last job was writing WebObjects software for the aforementioned music store.
