I started following @jquery on Twitter sometime ago, and they have provided a lot of great links and information.
One interesting link is to an article about methods for presenting information and creating systems to enhance user experience:
Delivering informative structure is the primary task an interactive user interface should be able to cope with. The more intuitive layout structure is designed, the better users can understand the content.
The jQuery foundation has created a new site showcasing designs that Use jQuery. They currently have only about 30 samples organized by effect/function category, but they do accept submissions so show off that great interface or behavior that you’ve created!
Jon Hobbs-Smith from the UK web development firm TVI Design has compiled a list of 25 tips to making your jQuery-powered applications easier to script and faster loading. While some of the items may be considered common knowledge (such as return false; for click events to prevent default behavior) the list provides excellent links and resources to people interested in using the Write Less, Do More JavaScript Library.
Considering almost all the recent updates to the framework relate to improving speed, why not take fullest advantage of them in making your application as responsive as possible?
