I have written a lot of questions and responses both as user 128932 and user 201044 in math, chemistry, biology, philosophy, etc. I have suggested a fair amount of really good ideas and have received a lot of responses that were kind of discouraging. A few notably encouraging remarks but mostly challenges.
I was wondering if any user had written some ideas that were considered so useful or potentially useful that some group from the real world , outside the stack exchange sites , actually wanted to useused the ideas and develop them to solvein some real world problemproductive ways? And if so weremaybe the ideas are actually useduser benefited from this?
