A "landing page" is but one part. It doesn't do anything except get contact information of people who express curiosity or interest, and a fleeting willingness to be talked with about what that page contains. It doesn't validate anything. What you do next with the people who expressed an interest on your landing page will validate your idea: getting to know the problem space better if you have prior knowledge, or getting to know the problem at all if you're an outsider, validating the need and the market, qualifying your potential users, selling or "pre-selling" or getting a commitment of some sort, and expanding. Are you a user yourself? If so, you have knowledge of your ideal customer and you can figure out how to reach them. Maybe you can still make the most out of this post and expose your idea, and update your profile with a means to contact you in case someone is interested. PS: Are you familiar with Microconf[0]?
