Yes, it's the back and forth that I highly value, and that is entirely absent (indeed, impossible) on SO. I am frequently saying things like "no, that's not right, ..." or "no, that's not what I meant, ..." or "could you keep this part, which seems good, but replace the rest with a different approach like ...". Think how rude it would be to micro-manage a volunteer answer on SO!
