Except for the UI Patterns site which does organize techniques by vague user goals, the other sites are too focused on tactics (Oooo, shiny widgets!), and not on UI/usability strategy. A UI strategy needs to start from higher-level questions, like, What is the user trying to do, and how do we best support him/her?
I much prefer Tidwell's book, which is well-organized and presented at a more strategic level. And it's (mostly) free too:
