Twitter is an open, real-time introduction and information service. On a daily basis we introduce millions to interesting people, trends, content, URLs, organizations, lists, companies, products and services. These introductions result in the formation of a dynamic real-time interest graph. At any given moment, the vast network of connections on Twitter paints a picture of a universe of interests. We follow those people, organizations, services, and other users that interest us, and in turn, others follow us.
