Topsy – Realtime Social Web Search Engine
http://www.topsy.com/

Topsy is a realtime search engine powered by the Social Web. Unlike traditional web search engines, Topsy indexes and ranks search results based upon the most influential conversations millions of people are having every day about each specific term, topic, page or domain queried. Socially generated content is the fastest growing source of information on the Web, with social graphs replacing PageRank as the new “signal” for identifying relevant content for consumers, impacting how consumers are exposed to, communicate and consume Web content. Designed for true web-scale search and powered by the largest searchable index of Twitter data, Topsy’s algorithms dynamically identify influencers within the Social Web for any searchable criteria, using these influence calculations to rank results. This means realtime search results are highly relevant & devoid of noisy stream of conscious content. Topsy displays realtime results for related terms & articles, trending topics, identifies experts (influencers) for any queried term and shows you trackback pages for everything in its index, displaying what everyone is saying about that query. And, we syndicate our results so you can insert relevant realtime content into your pages & ads to improve the consumer experience and increase monetization rates.
