Not all of the data on Twitter is publicly available. The textual contents of the tweets are found in the “text” XML element. We can also get a list of status messages from (and replies to) a specific user-in this case WolframResearch. Here are the users who made the posts in that document: This URL returns an XML document containing a list of 20 of the most recent posts to Twitter by all users. We’ll begin with a simple example that doesn’t require any authentication, the public timeline. You can probably guess where I’m going with this: Twittering with Mathematica. Recall that Mathematica can do HTTP (via Import or J/Link) and can also import XML. Twitter’s REST API is particularly interesting because it allows many operations to be performed using simple HTTP queries that return XML documents. Status messages (“tweets”) can be posted from the web, a mobile phone, or any number of desktop or mobile applications built specifically to interact with Twitter via its API. That last one trails off a bit due to the 140-character limit. 'Research Project Manager,Seattle, WA, United States: Penn, Schoen and Berland Associates is currently seeking qu. 'Who's up for cutting class today and hitting 18 holes? and the 19th too.' 'Can't wait to see Nigel, Laura and Ben later.' People use Twitter for all kinds of reasons, everything from staying in touch with friends to receiving announcements and support from companies with a presence on Twitter. Twitter could probably best be described as “ micro-blogging.” It’s kind of a cross between blogging and instant messaging. The 140-character limit comes from the 160-character limit of SMS messages, minus a few characters for things like the user’s screen name. The service poses a simple question: “What are you doing?” Users respond in 140 characters or less. The popularity of Twitter has really exploded in the past few months.
