As I said, C was my first language. As for Cocoa, it wasn't that bad considering by the time I really got into it there were plenty of examples out there (chances are, if you have a question about Cocoa for iPhone, it has been answered by now).
Well, the app is out there, but it is useless unless you are in the City of Pittsburgh. My approach to the startup is unconventional: I'm laying down pieces which will be played later on. It feels like chess. Not a chance a VC would ever fund us because of that. Yet it is no doubt as likely or more likely we will fail among startups.
Thanks. Do it because you love it.
