IBM: Where and when to use Ajax
My second IBM developerWorks article is now online: Where and when to use Ajax in your applications.
It's not a very technical article, so you can read it even if you've never programmed before. I talk about the benefits of using Ajax, and point out some problem areas that need special attention so that Ajax doesn't end up ruining your web site. It's essentially a summary of my Unobtrusive Ajax book.
The article was fun to write and I hope you enjoy reading it!
