AJAX
AJAX allows web applications to update the user interface without switching other pages (stay at the page) so that the web applications response faster.
There are two main technologies used in AJAX (JavaScript and XML).
- JavaScript, display and interact information dynamically in the web applications
- XML, use XMLHttpRequest to exchange and transfer data asynchronously with the server (in XML format)
Here's an article about AJAX, it also compares classic and AJAX web application models

Examples:
Google suggest
http://www.google.com/webhp?complete=1&hl=en
Google map
http://maps.google.com/
We may implement the search function which show suggested keywords and results instantly after user entering the word in textbox in PALE 2.0 (similar to Google suggest).
RSS
RSS is an easy and fast way to read news and contents (selected data) which are updated frequently.
RSS feed is the news and contents written in XML (the size is much smaller than a webpage)Users need a RSS reader to download and view the RSS feed.
RSS readers are available for PC, mobile phones and PDAs (mobile devices use RSS reader because the size of feed is small).
There is a free RSS reader.

We may make the comments about slide in a feed so that users can read the comments easily.
