What do Texas A&M University, Rick Perry, The New York Times, Barack Obama, and Joe Ura all have in common? We are all on Twitter.
Twitter is a social networking website. Users may post updates or "tweets" of up to 140 characters, which are delivered to followers and included in a web-searchable index of all tweets. As a user, you can, of course, follow your friends and use the website to deliver messages to one another. More importantly, though, you can follow publications, public figures, and other people and institutions, which will allow you to connect to a world of interesting ideas and information that is customized to your interests. In other words, you can use Twitter to help content you are likely to use or enjoy find you rather than you're having to find content.
You can create an account here. You are not required to do so for the class, nor is there any kind of credit (extra or otherwise) available for doing so. This is just a thing you might find useful.
I should caution you, though, that anything you post on Twitter may be made available to others online. As with all other social networking websites, including Facebook, you should take some time to adjust your account's privacy settings to meet your own needs and exercise careful judgment about what you post online.
