When pitching a startup idea to investors I got some of the best advice I've received. One investor told me, "You told us you were going to help solve a problem, you asked a bunch of people 'would you like me to make your life easier?' and they said 'yes', but you never showed us how you would actually do it. We want to see HOW."

That would be my critique of this. Would I like to find hidden gems where I live? Sure. But HOW are they going to help do that?
