Change in the (Yahoo!) Weather
I've been using My Yahoo! since its very earliest days; while many parts of this very web 1.0 "personal portal" have changed with the times, their detailed weather forecast pages had all the design panache of an interstate on-ramp. A smattering of ads, some gritty daily forecast graphics, and not much else to distinguish them from, well, anything.
Boy have things changed. Getting a dose of inspiration from the Yahoo Widgets (neé Konfabulator) design language, the detailed forecast page now has a crisp, inviting, easily scanned visual layout. Naturally, the weather page provides a link to the Widgets product itself ("Get Yahoo! Weather on your desktop"). It's now much easier to view the forecast content. Below the fold, two screenfuls of both regional radar and general weather headlines exist to provide related information as well as news of interest to explore. Nice to have. Let me put it another way; if this information has always been listed on detailed forecast pages, I never noticed it before the redesign.

Overall, it's a smart property cross-promotion and represents a concept I'm sure Yahoo is taking increasing advantage of, given its breadth of offerings.
