From what I have seen from the MIX09 web conference until today, there is quite a big interest in the Windows Live Messenger Web Toolkit and its features. Adding Messenger to your own website kind of amazes people and thus the interest in being able to do that is quite big as it allows you to very easily add very flexible support for integrating social networking into your site, while at the same time leveraging the huge install base of Windows Live Messenger users.
Recently, Robert Hess from MSDN Channel 9’s Knowledge Chamber discussed advantages and details of the new toolkit with Keiji Kanazawa, Program Manager for Windows Live Messenger, and I thought you might be interested in the video. Have fun watching!
