Now the question comes again how and where ?
Earning sources : I have seen so many websites paying just to like or post or write in your wall or status about other products. How basically this works ? When you are posting something in your facebook status your friend will be interested to review it. Then when they will give comment on it then his/her friends will able to see it too. When you post a link or a product or just write about a product and give its link in your friends wall your friends will review the product and others will also able to see about the products. So, the product is getting popular who is beside this ? yes this is you you are promoting the product just by your facebook account.
Exchange sources : If you have a website then you can exchange traffic by facebook. How when you like 10 peoples pages and they like yours your product will be in the top of the search engines because it is getting more views. So by this system you are actually getting popular also the person exchanging with you.
Points and prizes sources : Some websites give you points and prizes to like other products or website. Its just same as the 1st earning source and this is called a great way to earn some extra cash using your facebook account.
Basically this is just examples about your facebook account values right now.
So lets come to our point and lets talk about what will happen in the future ?
In the future you will be get paid $10 dollars just to share a product review in your facebook status everyday if you have 1000 friends in your account.Basically when you are showing the link 1000s of friends are watching it and the product is getting promoted by you.There will be more issues like sell your facebook account for $100 dollars with 1000 friends.
