I have been using apps such as "TripAdvisor" and "Yelp" to find new local places to go. I am sure that many of us(including myself) spend time on viewing photos to discover great places.
Why don't we become a restaurant reviewer?
I think "Tasteem" can serve a niche market for people who would like to make a profit with writing reviews and opinions on the restaurants.
Also, everyone who loves food can share and vote places and get a map of their favorite spots. People can follow and connect with each other in similar food tastes and personalities.
TL;DR
Let users can monetize with their reviews and opinions on restaurants.
