I'm kind of sad that you give tool-specific examples.

I love seeing things about someone's odd design process, studies on psychology and human-machine interactions, design theory applied to everyday experiences, product release post-mortems (that aren't weird "we be dead" self-promotion). The design of objects – or services – can be a source of great nonstandard insight, which carries over to interface design.

Basically, design as "going from an idea to a concrete concept" is what keeps me coming back. This and great discussions.

I couldn't care less about:

• What UX actually means (this week)
• Vacuous explanations on the latest visual trends
• Completely technical posts (they're useful, but not news for people who design)
• Product announcements that are just tease-pages asking for your email
• Clickbait links
• ^ So, most of FastCo at this point
