Hailstorm? Scoble has the partial scoop on Hailstorm, the new MSN Mesenger and related technologies/services. Sounds intriguing: "The HailStorm version of MSN Messenger will have a few new tabs that can hold Web services. Ebay and other companies are planning to have services that fit into these new tabs. Oh, you could write your own service too. I could send content via SOAP straight to your MSN Messenger. Or, I could build a service where you could interact with my stuff." Of course, Messenger is still in the vast minority in terms of IM market share, so it will take some compelling applications to make building applications compelling.
