Patterns and boilerplate

A couple of old ones, and a couple of new ones. I really think patterns and boilerplate are a key component of the semantic approach, and for some reason they're cropping up in my daily reading today.

• Designing social interfaces - a Wiki with about 100 user interaction patterns; also a book.
• UI patterns - I'm pretty sure this has been linked from this blog before.
• Flask boilerplate
• Backbone.js boilerplate
• Pattern tap - these are more design elements, perhaps.
• Yahoo! design pattern library, of course
• Patternry open UI patterns
