If you're always using your Windows Live Messenger for IM'ing with friends, then you're going love this news! The Windows Live team has just announced the introduction of a new Facebook app that lets your friends chat with you via Windows Live Messenger right from your Facebook profile page. When your friends visit your profile page, they can start an IM conversation just by clicking on the chat window. Then, their IM messages will come directly to your messenger client running on your computer. And, don't worry, your chats are private - others visiting your profile won't be able to see what you're saying or view message history. The new app also lets you add the owner of the Facebook profile to your contact list in WLM directly from the app itself. To add this to your Facebook profile, click here.
