"Today we released the Shoposphere and Pick Lists beta, plus enhancements to our core shopping search capabilities, which we hope you'll try out during your holiday gift-giving spree," says Yahoo's blog.
"The Shoposphere and Pick Lists are examples of social commerce. We believe the community of shoppers is one of the best sources for product information and advice. The Shoposphere is a place to discover interesting and cool products thematically arranged into Pick Lists by other shoppers. It's always changing. It includes new lists in a "product stream" and highest rated lists which are a fun way to explore new products and trends. The Shoposphere will continue to evolve as a hub for other types of user-generated content."
