Social E-commerce and Social Network marketing
Social e-commerce is commerce-based on the idea of the digital social graph.
The digital social graph is a mapping of all significant online social relationships.
The social graph is synonymous with the idea of a “social network’’ used to describe offline relationships.You can map your own social graph (network) by drawing lines-from yourself to the 10 closest people you know.
If they know one another, draw lines between these people. If you are ambitious, ask these 10 friends to list and draw in the name of the 10 closest to them. What emergers from this excise is a preliminary map of your social network. Now imagine if everyone on the internet did the same, and posted the results to a very large database with a Web site. Ultimately, you would end up with Facebook or site like it. The collection of all these personal social networks is called “ the social graph”
