Social Commerce
Defined by Steve Rubel in the Micro Persuasion blog athttp://www.micropersuasion.com/2005/12/2006_trends_to_.html
"Social commerce can take several forms, but in sum it means creating places where people can collaborate online, get advice from trusted individuals, find goods and services and then purchase them. It shrinks the research and purchasing cycle by creating a single destination powered by the power of many.
One shining example of social commerce is Yahoo!'s Shoposphere. As David Beach from Yahoo describes it, the Shoposphere is a place to discover interesting and cool products thematically arranged into Pick Lists by other shoppers."
