The main reason behind my question was that I have a form of Ideas Journal where I write either problems I see or possibilities of what can be created. From time to time I read it and try to figure out if there is something truly valuable to pursue. For sure setting up a signup page could be one way of doing that. And now that I re-read your comment I am thinking that I could make a script to automatically generate these kind of pages for my ideas. This might be a good way to automatically test most of them. I also take great inspiration from your examples.
