Today a question came to my mind that which site will be more profitable a gambling site or a dating site? Actually I want to find out that in which place people are more interested and where people mostly want to go to get fun.
There is not a such rule.
While some might make ton of $ with gambling, other would do with dating site.
It depends on your (or your group's) skills to create, market and maintain your products.
There is simply no substitute for hard work when it comes to achieving success.
