The only merit I can see in an app like this is that once the snap shooters find the tripod holes and take their pictures, they will be so p'd off that their photos don't even come close to what they thought (or saw previously) that they'll give up on photography and leave it to those who are serious about creating truly compelling photographs.
Unfortunately, until that happens all these wonderful, unique places visited by the hordes will be trampled to death. That's my greatest concern with apps like this - by the time they, and hundreds like them, find the tripod holes they will have clogged highway pull-offs, left their litter behind and trampled acres of what might have been pristine nature - all so they can tick a list and have a so-so picture of a beautiful location.
I happily share locations, but only with people who have the utmost respect for the sanctity of these beautiful places.
