Finally, the official Windows Live Messenger App for Facebook is here. There’s been quite some unofficial apps present, but I never installed them because I don’t really like to give up my password and Live ID to some third party dude. Even if he doesn’t harvest the addresses, I still think it’s a bit tricky. BUT, no more of that. The official app is here! On April 29th, Microsoft released the Windows Live Messenger Facebook Application. Members of Facebook can chat with their friends using this application that runs on the Facebook site. Once you have installed the application, people who have access your Facebook profile page can initiate IM conversations with you (it is based on the Windows Live Messenger IM Control. One side of the conversation happens on the Facebook site, the other side in the WL Messenger client). You can invite your Facebook friends to add the application and join Windows Live Messenger. The application also shows the WL Messenger online presence of your Facebook friends who have installed the application (it is based on the Windows Live Messenger Presence API).

The application will be promoted worldwide in partnership with RockYou. RockYou will only promote the application to existing Facebook users. This is an opportunity for Windows Live Messenger to acquire new users.
