Question about jQuery and reload a page
<p>this is a noob question, so, be generous with me please.</p>

<p>Take for example Twitter. There's an input text form at the top for writing tweet and below the tweets list. If you write a new tweet and click "Tweet" button, you'll see the your new tweet instantly in the tweet list, without reloading a page. I know this is a banal situation but by the way I want to ask you.</p>

<p>I've a page with a form at the top and below it there's a message list. When you fill the form and submit a new message the page it reloads and you see the updated message list with the new message. I want implement the same technique that Twitter use. Maybe should I use jQuery, and send data to a page with <code>$.post</code>. Can you explain me something about?</p>
