Web App Design Anti-Patterns
Slideshare is a great learning resource. There are presentations from top-level presenters in a number of fields (particularly Web design and development) posted there, although you sometimes have to wade through the litany of "Hot Brazillian Girls" slideshows that never quite seem to go away. You can subscribe to their very convenient RSS feed of latest presentations submitted to the site, or the most viewed presentations within a given day or week or month, and so on. I usually review one or two presentations a day on the site.
Bill Scott, the Director of UI Engineering for Netflix, posted a great and detailed presentation on "Designing Web Interfaces: Principles and Patterns for Rich Interaction." What's really useful about this presentation is not just the depth of examples but also his pointing out anti-patterns in Web application interface design. Anti-patterns aren't well discussed in this area, and I think he makes some great points about common approaches to interaction which may be less helpful than we expect them to be.
The presentation is below, but you should definitely head on over to Slideshare if you haven't already, as there's a wealth of useful presentations there.
