Over the past decade we have seen the web change in dramatic ways. Static html web pages are facing a stiff challenge from blogs and video clips. The notion of relations, networks, and reputation which were largely built on web page linkage have matured into community voting of sites and documents. Social network sites have become common and the notion of identity, trust, and reputation are commonly defined between users and the pages or objects they interact on. As eCommerce matures and blends with social networking search, classification, and recommender systems take new shapes. Social trust, reputation, and identity form key entities that help commerce thrive in the generation of the social web. Further, peer-to-peer networks provide for new platforms and challenges for search and social network structures. eBay, as one of the earliest known social commerce companies, provides a great context to study these concepts as applied to a marketplace. In my discussion I will touch upon many of the topics mentioned here as we have been studying them at the research labs.
