OP here. No real money, just a few good ideas. I'm an engineer and programmer (started designing mainframes at IBM) but long retired from the day to day issues of design and coding, especially distant from modern device programming. Like a barely countable set of such people, I'd like to lure a programmer in with a good idea and the belief that it could be financially worthwhile in the long run. How to do that without being too vulnerable to a hit and run completely escapes me. Y'all have given me some threads to follow, thanks. More specific individual replies coming up. I sure wish ycombinator had a notification option for threads you start or comment in. That would facilitate longer and more productive threads. Am I just missing it?
