Ajax is the new way to add interactivity to your site. If you don’t know what ajax is I will explain it. It is a way to talk to the server and run server side scripts without reloading the entire webpage. It uses javascript to accomplish this. I don’t think it is a good idea to build your entire site using ajax but it can work great for things like star rating and small apps like that. Just like I don’t think it is a good idea to have an entire site built in flash.
There are some disadvantages to ajax. The search engines won’t be able to index anything that is produced on the page using ajax. So if your articles are being called by ajax you probably won’t get a lot of traffic from the search engines. So don’t over do i, but it is definitely a good skill to have!
