title: auto updating a list of items with jQuery
body: <p>I'd like to create a list of the latest content on my website and I'd like it to update every 3 seconds. New items have to be added to the top of the list with an animation. I't should look like the list of tweets on twitter's index page (the index page for not logged in users).</p>
  
  <p>I'm familar with jQuery, and I'm wondering if somebody know a plugin that I can use. I also use PHP to send the info from the server, so this wil not be a problem, I just need the jQuery code to handle this.</p>
  
  <p>Do you, guys know a nice jQuery plugin that can do this for me ? Thanks!</p>
