It never occurred to me that anyone would be shy of "stealing" an idea off a public forum. The expected value of a raw idea is negative. One invests time and money in execution only to discover that the idea is not viable. One ends up regretting ever having heard of it.
At the very least, a courtesy e-mail might be nice?
I am not a programmer (as of now), and as I explore how to execute an idea, I am reluctant to share a full-scale plan and specs of the site I wish to create. Hence, the ambiguity in my original post.
I would love to share a detailed plan of my idea with the community, to garnish feedback and establish credibility. However, there is nothing to stop someone from taking the plan that I have spent hours developing (which I consider intellectual property, equal to the actual programming), and improving upon the idea and writing the actual code to make it happen. I understand that "ideas" are merely just that, and that executing an idea is where it counts.
How much disclosure can you provide about a project to solicit feedback, without having your idea "borrowed" for development?
It would be nice to have the text edited as per aintahacker's post to make it more clear.
