The sentiment that ideas are worthless without execution is generally true. This can be easily explained, as "execution" can be broken down into two components: actions, and details. Action is obvious: no action, no product. Details, well, are "where the devil is." A really good idea will include enough details, that it spills over into "execution." It's not just an idea-market. It's an idea-market where people submit via a form that looks like this, click that button, get scored this way. We will launch it by doing this, talking to those people, and focusing on this sector. We will convert this into physical and monetary value by selling this service. Now, that may be an idea that is worth something. While you have described certain approaches, until you have a very sharp focus that describes exactly how to get from point A to B (nothing to full product), which means not just "one way to do this is...", but "this is how we will do it," then the idea really is not "executable."
