Why not just using ajax for Page Requests to load the page content?

Question

Many web pages load all of their content to change very little information.

Now I would like to know why shouldn\'t the developers just use ajax for the main page re

Answer 1

One thing is that you want content to have a static url, you want people to be able to link to your pages, bookmark them, etc.

If everything is ajaxified, this could be tricky and/or tedious.
