I think this secrecy is not your friend.

I won't patronize you with how the idea doesn't matter etc. I am sure you have heard it all before and can make your own decisions.

But what I will point out here is that the idea is so vaguely described, that it is completely uninteresting. I think a really good partner would want to know exactly what the thing is before giving up energy and time to jump aboard.

I think of all the great people I know, and I can't think if any of them would reach out to someone on the basis of "Post-Monetary, Gifting Economy" etc

Although HN is enormous so maybe you will have some luck.

Wish you well.
