How Do You Tweet or Twitter?

Once you have registered with Twitter all you do is answer the question: What Are You Doing? Submitting your answer is a tweet or sometimes called a twitter. Twitter is really the correct term since the whole site is named after how birds communicate (twittering), but tweet has grown to be a more popular way to say What You Are Doing. You can put whatever you want in the box(including urls), but it has to be less than 140 characters.  If you want to tweet an image you have to link to an outside source like Twitpic or your own personal blog, etc.
