If zacharyvoase wants to spend his precious free time educating people who haven't done any due diligence to learn how to build a secure web app, that's his prerogative. But I don't see it as a good use of his time - there's already tons of resources out there that will do a better job than zachary. Is HN supposed to be a newbie education destination?
