So, why did they do such a bad job integrating with Messenger? I really want a real-time social network, with blogging, photo sharing (a la Hello), music sharing (a la last.fm), and instant messaging. They have all the pieces. But what they need is to map my friends into the messenger buddy list. Everything should work in the obvious way, but when I click on a Messenger online icon it just brings up Messenger, not an IM session with the friend I just clicked on. And the 360 friend might not be on my buddylist, although they are an approved 360 friend. Ugh.
