Twitter is a free social networking and micro-blogging service that enables its users to send and read messages known as tweets. Tweets are text-based posts of up to 140 characters displayed on the author’s profile page and delivered to the author’s subscribers who are known as followers. Senders can restrict delivery to those in their circle of friends or, by default, allow open access. Users can send and receive tweets via the Twitter website, Short Message Service (SMS) or external applications. While the service costs nothing to use, accessing it through SMS may incur phone service provider fees.

TinyURL is a web service that provides short aliases for redirection of long URLs. Kevin Gilbertson, a web developer, launched the service in January 2002 so that he would be able to link directly to newsgroup postings which frequently had long and cumbersome addresses.

The TinyURL homepage includes a form that’s used to submit a long URL for shortening. For each URL entered, the server adds a new alias in its hashed database and returns a short URL such as http://tinyurl.com/2unsh in the following page. If the URL has already been requested, TinyURL will return the existing alias rather than create a duplicate entry. The short URL forwards users to the long URL.

TinyURL also offers an API that allows applications to automatically create short URLs.

Short URL aliases are seen as useful because they are easier to write down, remember or pass around, are less error-prone to write, and also fit where space is limited such as IRC channel topics, email signatures, microblogs, certain printed newspapers (such as the .net Magazine or even Nature), and email clients that impose line breaks on messages at a certain length. People posting on Twitter make extensive use of shortened URLs to keep their tweets within the service-imposed 140 character limit.

Starting in 2008, TinyURL allows users to create custom, more meaningful aliases. This means that a user can create descriptive URLs rather than a randomly generated address. For example, http://tinyurl.com/wp-tinyurl
