Sightix : social networking meets search (website)

When you search for something using the Sightix technology on a social network, it searches the content of everyone you are connected with, and ranks results gleaned from each user based on the strength of their connection to you. Ari Gottesmann, vice president of Sightix, gave me this example: Say you're searching for a nightclub. The clubs your friends talk about will get a higher relevance than your friends of friends. It's much more likely that this ranking will yield results that work for you than searching a general engine that doesn't give extra weight to your friends' recommendations. The product also works as a people search engine of a sort. If there's a good result from someone way out in your extended network, this tool will help you connect with them. The Sightix company, originally in the business intelligence business, has given its social search product a rich and complex interface.
