var url = "http://twitter.com/status/user_timeline/RedWolves.json?count=3&callback=?";
$.getJSON(url, function(data){
    $.each(data, function(i, item) {
        $("img#profile").attr("src", item.user["profile_image_url"]); 
        $("#tweets ul").append("<li>" 
                                + item.text.linkify() 
                                + " <span class='created_at'>" 
                                + relative_time(item.created_at) 
                                + " via " 
                                + item.source
                                + "</span></li>");

  var twitter_user    = 'lupomontero';

  // Enabling caching

          var date_now   = new Date();
          var date_diff  = date_now - date_tweet;
          var hours      = Math.round(date_diff/(1000*60*60));

          var tweet_html = '<div class="tweet_text">';

It would be more efficient to handle the parsing on the server side, but I assume you're building the site entirely using client-side technologies?

An example of some JavaScript code:

// Store your JSON data in a variable  
var yourJSON = {
    "animals": [
        {"type": "dog", "name": "Paul"},
        {"type": "cat", "name": "Ralph"},
        {"type": "bird", "name": "Jim"}
    ]
};

// Retrieve and store specific data from the JSON
var PaulsType = yourJSON.animals[0].type; // Returns 'dog'
var BirdsName = yourJSON.animals[2].name; // Returns 'Jim'

When working with Twitter, there are multiple levels of nesting, so you need to access the data accordingly. For instance, if you want to retrieve information about your followers, the structure could look like this:

[{"statuses_count":527,"profile_use_background_image":true, ....
....
,"status":{"place":null,"retweeted_status": {"place":null,"coordinates":null,"retweet_count":"100+","truncated":false,"text":"BLAHBLAHBLAH" .....

This is just displaying an example at index 0. To extract the text of your most recent follower's tweet (in this case, a retweet to demonstrate encapsulation), you can use JavaScript like this:

var yourJSON = {insert Twitter output here};
var firstFollowersTweet_retweet = yourJSON[0].status.retweeted_status.text;

// To get the raw text whether it's a retweet or not
var firstFollowersTweet = yourJSON[0].status.text;

BOOM!

Check out $.json, a specialized method designed for handling JSON data. It performs an AJAX request and automatically converts the returned JSON into an array that can be utilized in the callback function.

It's more advantageous to access the Twitter API from the client-side rather than the server side. When accessing their API on the server side using PHP, there is a risk of the server's IP being rate-limited by Twitter. Additionally, it appears that Twitter has not officially published their rate limits.

Utilizing the REST API may not be beneficial either due to the low limit which would hinder developing a site for an unknown number (potentially large) of users. This lack of scalability is a major drawback.

Using JavaScript makes it simpler to have the client request the data instead and avoids the limitations faced with server-side requests.

While it is possible to OAuth each client and utilize their own API-Limit, it can be quite cumbersome just to retrieve some tweets. Opting for a more generic approach seems like a simpler solution.
