to the Electronic Commerce Dictionary, electronic commerce is defined
as "the conducting of business communication and transactions
over networks and through computers. Because the users of these
computers generally are human, most e-commerce sites have developed
a sense of 'community' in their structure.
the most famous use of community in E-Commerce sites is Ebay. The
strength of this online auction environment is the feedback and
rating system they employ to allow buyers and sellers to comment
on their transactions. The more you buy and sell successfully the
higher your rating. This, in turn, gives new users a sense of confidence
in purchasing an item they cannot physically inspect from someone
who is not seen face to face.
