My team at Microsoft put 3 new msn.com international homepages live last week that embrace AJAX technologies for page rendering. These homepages (found at http://malaysia.msn.com and http://ch.msn.com) load their contents asynchronously, and allow real-time interaction with certain modules on the page. Adding new weather cities and RSS feeds no longer requires a page reload, instead loading the data straight into the page.
The sites are in pilot mode right now, but we will be rolling out many more international version starting September.
