Whozat?, The People Search Engine
http://www.whozat.com/

Whozat? is a one-stop-shop aggregator that allows users to find other people in social networks, blogs, photo and video sites and on the WWW. A blind evaluation of the relevance of people search results for Whozat?, Google, Yahoo, Ask, and three other people search engines threw the following preliminary but statistically significant results for a list of ordinary people compiled by a third party: Whozat? beat every other search engine, yielding the most relevant results, as evaluated by the searcher, almost three times as often as all generic search engines and more than five times as often as any other people search engine. Whozat? achieves this through a combination of broader reach and proprietary algorithms. Whozat? also boasts a people-centric UI, machine vision to find photos of the people you look for, automatic tag extraction to describe a person at a glance, and It’zat and Not zat feedback buttons that allow searchers to tell Whozat? whether a person, URL or tag is relevant or not to their search, immediately customizing results accordingly. These interactive features make searches with Whozat? a conversation rather than a one-way street. Whozat? even allows searchers to specify the age (‘zat old?), location (where ‘zat?) and/or sex of the person sought, and finds related people, too. Unlike sites which mostly contain information provided by users, Whozat? is a true search engine, finding information and photos of people without any prior instruction needed.
