Our esteemed colleague from the Developer Platform Evangelism team, Don Campbell created what he calls a mind map of Office Live. It's a really neat way to visualize all the pieces that make up the Office Live Application Platform... from the technology itself to the dev guide and forums and blogs that support it.
Check it out and send him your feedback. It may just open your eyes (and mind!) to some new possibilities about how to hook up the pieces in the Office Live ecosystem.
About the only thing I see missing is the recent release of our Time Card sample app that I blogged about a week or two ago.
