Tsavo Media, a company focused on the delivery and monetization of niche content to digital consumers, introduced Twithority,"Twitter Search by–Authority," a new search engine for the microblogging service Twitter. Twithority returns Twitter search results, looking back as many as 1,000 results. It sequences results by rank, with highest ranking users first, and time (with most recent tweets first), within the top 10,000 Twitter users. Tsavo will integrate Twithority into its Daymix network of consumer content sites. Twithority will serve as an informal metric for Tsavo’s content sites, along the lines of Google’s zeitgeist feature.
