Social search concept interesting

PR Newswire
"Multiply Inc has introduced the first search engine that finds
information that's been published in one's social network. Conventional search engines attempt to catalog the Internet at large and display search results purely in order of content relevance. Multiply's search returns content published by people that have a relationship with the person searching, and
relevance is based not just on the content, but also on the social
relationship of the content owner to the searcher."
