Fair comment, but I've been programming for 10 years (although I know that's not what your point is getting at). Your fears are fairly moot though, the app isn't networked (yet) and is fully self contained meaning that no one has access to your data except for you.

If I get to a stage where there are enough people demanding networking then I imagine my age won't be much of a concern any more.

I think this is a good lesson. Whatever you show in your video you are using to market your product including you. Just do a video with your voice and screen capture and you'll probably be better off. I felt the video seemed semi-unprofessional.

Could I ask in what made you think it was semi-unprofessional? I'll admit it was a very candid video, but I can't see how you'd get to unprofessional.

I watched it until the point where you just rolled in and started chatting. It's hard to do these types of video.

As I said I was aiming for candid. But you're entitled to your opinion and I appreciate the feedback.
