Maybe support isn't a great word here. Maintaining software goes way beyond just supporting someone. Staffing and hardware requirements aren't terribly important for greenfield development without any users yet. New products can be brittle and constantly in flux and that's probably ok. Actually scaling the product once it exists and have users, building out new features without disturbing existing workflows, that's the hard work. Which do you think is harder, inventing twitter as the fail whale product, or going from that to a hundred million users without disturbing the customers you got? I can't imagine the difficulties can even compare.
