Web2.0 Design Guide
Here's an interesting site that I came across this morning while browsing - The Web2.0 How-to design guide. . The guide is a summary of many of the common features of typical "Web 2.0" sites, and provides some useful pointers for those interested in interface design. It's worth a read - such a lot has changed in the field of design since the days when I first studied it!
In a similar vein, Jakob Neilsen has posted his 2006 list of Top10 Mistakes in Web Design. Since 1996, Neilsen has compiled many top-10 lists of the biggest mistakes in Web design. (Links to all these lists can be found at the bottom of this article.) This article presents the highlights the very worst mistakes of Web design.
