The idea looks very similar to Alias (if I am not mistaken) social network where authors of context also get paid with tokens . But that is certainly a nice idea
In social networks for tourists too much superfluous and personal information. I hope that after running this application in contests will win the most colorful and detailed videos that will describe the tourist place, and not what was eaten tourist for breakfast.
Well, the theme of food and where you can eat is also very relevant. For this reason, I think the content will evaluate the community itself and determine its usefulness.
