Hey, how many experts do u see in the future on your platform? Have u done a social survey, how much are people ready for this solution?
In fact, it can be at least a billion users. If technology will be popular - it will be something like instagram or facebook. That is, "must have" on the smartphone

May be it will be so may be not. Only time shows how it will be. I with the success to the project. Good luck.
