Although I enjoy programing a lot, I am also very interested in user interface design and improving the user's experience. Therefore, I am thinking of moving my career in the direction of usability. I would like to try to teach myself as much as I can about usability. I've already read the classic "Don't Make Me Think" by Steve Krug, and I'm wondering what other resources are out there.
What books/ websites/ blogs/ etc. would you recommend?
I highly recommend Donald Norman's articles. He's like the godfather of User centered design. And especially his book - "The Design of Everyday Things" (I studied it in uni at a Human–computer interaction course).
You should also try going back to school if you are really serious about it and take some HCI courses. John Hopkins offer a fast track Software Engineering course that specialize in HCI. There might be other biggies too but going back to school is a pretty good investment for your career in usability.
Here is the bookself I learned and learn from. You don't necessary have to go back to school if you can practice in real. The list order represents the suggested reading order. Starting with the Krug book was a good ignition. You will enjoy GUI Bloopers next.
Rosenfeld Media books can give you practical in deep knowledge also.
