The team I work on has just finished and released a major upgrade of the Microsoft Learning Site.

Highlights include:

• Totally new UI
• Enhanced filter/tag based navigation through the offerings
• RSS Feeds from stock categories as dynamic feeds based on your selected set of filters/tags
• Ajax-ified for a much nicer user experience
• More web-aligned urls so you can bookmark things much more effectively than in the past
• Multiple view and sorts
• Localized UI and Localized Offerings
• Updated My Learning to make it easier to navigate through and manipulate your learning items
• ... and a whole bunch more!
