Precisely. I think people sometimes get caught up in their own ideas and think they're going to change the world or be stolen. I am not ashamed to admit maybe 7 years ago I kind of thought like this. I built things in secret because I was so afraid of my ideas being stolen.
I actually discovered later on that telling people your ideas and as many people as possible leads to a better end result, as your feedback pool deepens substantially.
There is a reason most companies and venture capitalists refuse to sign NDA's from starry eyed start-ups and developers, because nobody makes an acquisition or investment into an idea.
.....i see your logic, now see mine.
If your idea is already a few steps ahead, its fine to share.
No idea is unique , everyone ispretty much doing everything .
However, from experience, its best to speak with private investors and keep part of your plans secret until you're good to go.
There is a reason companies secure patents before releasing a product .
Running a business is hard, especially when one has little cash
If it were $1m up for grabs, then i would be inclined to risk sharing it to the world.
