This isn't difficult in my country. We are still bound to (or give value) growing up in a combined family while caring and having affection with each other. As we grow up and remain together with our elders, we get to learn a lot of social values. With social values, there comes a sense of getting together. We are a very religious country with so much of our faith converting into social gatherings. Often another man or woman is seen knocking at the door asking for some kind of gathering. The gatherings may be depicted as socially religious. Above all, we have a mentality not to deny anyone on him inviting us. Why? Because when we invite them, they will also deny. We have such customs and rights which require social gatherings without a solid reason behind them. Just to mention, on the full moon night, all of the woman from our colony sing ballads or folk songs with a 'Dholak' in the praise of God. The same happens on the new moon day, when woman gather together in the morning and go to take bath in the pious river nearby.
So, rather depicting where to crowdsource, we must first implement 'why and how to crowdsource'.
Thanks....
