Why AJAX Sucks (Most of the Time)

Jakob Nielsen wrote an article about why AJAX sucks. I personally don't agree with all of this article. He states that development is hard, well the same thing was the case when XML first came out it was hard and labor intensive. But then again AJAX is not for the Frontpage crowd. There are some good points in the article; people like with everything else will overuse this technology so that they can claim “we use AJAX”. I think one of the best ways to use AJAX is in paging record sets. While a user is looking at a certain sets of records you can already pre-fetch the next page, so that when he clicks next the records will appear instantaneously. Two good examples of applications using AJAX are Gmail and Outlook Web Access.
