And a few weeks after George's post even more was revealed in posts such as this one about FeedSync and Live Mesh where we find out Congratulations to the Live Mesh team, who announced their Live Mesh Technology Preview release earlier this evening! Amit Mital gives a detailed overview in this post on http://dev.live.com. You can read all about it in the usual places...so why do I mention it here? FeedSync is one of the core parts of the Live Mesh platform. One of the key values of Live Mesh is that your data flows to all of your devices. And rather than being hidden away in a single service, any properly authenticated user has full bidirectional sync capability. As I discussed in the Introduction to FeedSync, this really makes "your stuff yours". Okay, FeedSync isn't really AtomPub but it does use the Atom syndication format so I count that as a win for Atom+APP as well. As time goes on, I hope we'll see even more products and services that support Atom and AtomPub from Microsoft. Standardization at the protocol layer means we can move innovation up the stack.
