Ajax offers the possibility for a better user experience for content authors as well as site visitors for the Web CMS world. It updates without full page refresh.
• Continuous Feel: Traditional web applications force you to submit a form, wait a few seconds, watch the page redraw, and then add some more info. Forgot to enter the area code in a phone number? Start all over again. Sometimes, you feel like you’re in the middle of a traffic jam: go 20 meters, stop a minute, go 20 meters, stop a minute … Ajax offers a smooth ride all the way. There’s no page reloads here - you’re just doing stuff and the browser is responding.
