bare bones method for grabbing and updating a users latest tweet (with no error handling whatsoever)

gistfile1.js

$.ajax({
  url: 'http://api.twitter.com/1/statuses/user_timeline.json?screen_name=someonesplendid',
  dataType: 'jsonp',
  success: function(data) {
    var tweet = data[0].text;
    tweet = tweet.replace(/(http\:\/\/[A-Za-z0-9\.\/_]+)/g, '<a href="$1">$1</a>');
    tweet = tweet.replace(/@([a-zA-Z0-9_]+)/g, '<a href="http://twitter.com/$1">@$1</a>');
    $('#tweet').html(tweet);
  }
});
