I feel like I'm all about "Yahoo" tonight. Considering I don't use their services much (not sure why honestly), I'm excited to see how more open they are becoming. One recent addition is their new design library. Essentially it's what their developers use for their various web properties to bring consistency across the Yahoo brand. Although not yet finished, it's great that a big company like Yahoo is opening up to show how they do software design. I particularly like how each design pattern is short, simple, with brief text and examples as needed and available. Check them out if you're interested in usability.
