For the curious, essentially this is done by appending a <script> tag
to the <head> element of the current document, something like this:
<script type="text/javascript" src="http://twitter.com/statuses/
user_timeline/some_user_id.json?callback=someCallback"></script>
The browser sees this new script tag (more accurately a DOM event
fires), goes and gets it, and Twitter returns something like this:
<script type="text/javascript">someCallback([some data])</script>
causing a call to someCallBack() with the data from the API call,
which runs in the browser.
Cool, huh?
(I can't promise this is how jQuery does it - but this is how I do
it.)
