I just returned from a 10 day vacation in Israel with my girlfriend. While traveling I met a guy named Elazar Heim, who is a Product Manager for Sightix. Sightix is a social search platform offered as a service for social networks that returns personalized relevant results to their users. Google has been trying to improve the relevancy of search results via personalized search for a while now. There is no question in my mind that this type of technology is the next step in the evolution of search. As social networks become a ubiquitous feature of being on the internet, Sightix social search will become more practical. Could Facebook’s implementation of this type of social search engine be the real Google Killer?
