Twitter purchased Summize these days, in order to improve the search of the Twitter network, for relevant topics.
Twitter is a free social networking and micro-blogging service that allows users to send updates (otherwise known as tweets) which are text-based posts, ranging up to 140 characters long, via SMS, mobile, or Twitter’s web site
Twitter blog confirmed this aquisition: “We’re excited to announce that Twitter has acquired Summize—an extraordinary search tool and an amazing group of engineers. All five Summize engineers will move to San Francisco, CA and take jobs at Twitter, Inc. This is an important step forward in the evolution of Twitter as a service and as a company.”
Summize offers an API so other products and services can filter the constant queue of updates in a variety of ways. The Summize service and API will be merged with our own and integrated under the Twitter brand.
Twitter can connect groups of people in critical situations, and there are a lot of such examples. The American Red Cross uses Twitter to exchange minute-to-minute information about local disasters, including statistics and directions.
