Foodspotting is simply because I do not visit restaurants as much as I want to. Even though that is stated I do use the foodspotting app as it makes food more social from a online perspective. Foodspotting is becoming the foursquare for food. I do personally think Foursquare did miss their target here and they could have kept Foodpotting out of the game however they failed at it. From a user perspective this is not a negative thing as Foodspotting is doing a great job.
Foodspotting is one of the startups started by real and true believers in the subject and that is what you see in the final result, a great passion of developing a real cool and great product.
