Steemgram: instagram based on steem

Hi everyone!
My favorite social network is instagram. There is a lot of interesting people, who writes interesting posts with beautiful photos. Every day I'm watching and "liking" thousands of photos. But where are those likes?

So I want to develop a new application. App, that would be based on steem. User can post a photo like in instagram, share it with his friends and other people, but instead of red hearts, he can earn money. What do you think about this idea? :)
