Don't get me wrong. I don't think the world needs another jobs board but at one point airbnb sold cereal boxes so who am i to judge on what a persons ambitions will look like in 12 months time if they continue to learn and get some feedback. I mean, if they are reading the thread there is a bunch of feedback here they can assess.
Everyone here who is commenting on scaleable systems had to start somewhere, i would bet for many that start was not with something that was at least halfway functional and could accomodate users.
