I think he should do the simple idea first, release it right away, then either expand that idea, create another app on facebook, or simply do NO FURTHER MODIFICATION at all. It doesn't HAVE to be this all-encompassing time-consuming project to be worthwhile. Why debate what may happen 3rd or 4th generation when he needs to create something in the first place? He's excited about a simple idea, and that is what he should do. Why should he worry about what he may or may not (if he chooses to) do in addition to the original idea he's excited about? That's a bad trap to get into. Thinking that one needs to have everything planned out is why few people ever start or finish anything on their own initiative. Does it solve a problem? Is it something you will use? Is it something you can be proud to show others (e.g., it's not porn)? Are you excited about it right now? Then, create it. If thousands of other people like it, great! If not, it will still save him $150 a year and give him something to talk about. Not every idea has to be stretched out to the point it might take you 6 months to create (which translates to 1 year actual time.)
