Internet should be smoother. And in that case, every website should use AJAX as much as possible. Do you know how much I hate to refresh when I was using Dial-Up connection?
Using AJAX will reduce data transmission. And It will attract more users. But AJAX is not the only solution to this. We should make the internet a better place. Internet browsers compatibility on HTML5 will help this too.
HTML5’s video player will reduce using Flash Player. Then we wouldn’t need Flash plugins anymore! Thank you HTML5!
