Bottom line: Justin Bieber = traffic. I fully intend to use this to my advantage, and none of you can do anything about it. The purpose of today’s video tutorial is to demonstrate how to use a scary set of words, “asynchronous recursion” to continuously display updated tweets about the great Biebster. And then finally, we’ll hijack these tweets to make them look as if they’re referring to Nettuts+ instead.

// get the ball rolling

$.each(results.results, function(index, tweet) {

tweet.text = tweet.text.replace(/(Justin )?Bieber/ig, 'Nettuts');
}

return false;
