Ebay: community or bazaar?

My research topic is on Ebay. I will be discussing multiple perspectives of it, as well as the positives and negatives that Ebay brings to the people. There is no doubt that Ebay is an example of new media because it brings community, communication and collaboration. The debate of my topic is whether Ebay is a community or a bazaar, i will break this down. I will also let people know whether this vast system makes it harder or easier for individuals on multiple levels. Ebay has affected the online market and has brought a vast amount of items to the reach of the people. This is the area that interests me.
