@Anitah – thats your view, but if you see the best employee advocacy programs across best MNC’s your view will change.

@ptrikha15 yes absolutely. With companies which has more than 10,000 people and most of the IT companies have huge employee strengths across the world, they can easily achieve this if they have the right R&R for it. 

Try Gaption, there few marketing influencer sites/apps as well which lets u earn through social sharing etc.

Facebook has long term plans. With more then 1.6 billion users, its not going to give it easily to its competitors. I think pay sites wont reach that level as there is  lot of negativity associated with it, best eg was TSU.

So i guess your estimation of 5-6 years can be true. I feel not more than next 2 years.
