With the release of Windows Live Essentials beta 2 Windows Live Messenger received a new feature which people have been craving for a while: the ability to chat with Facebook friends. This has been expected as in the previous beta there was some Facebook integration mostly having to do with status updates, but it did show contacts as well. The messenger also has connectivity with many other social networks truly making this a social hub.
Directly from Windows Live Photo Gallery you can upload to Facebook, YouTube, and Flickr, as well as the company's own SkyDrive. Then from Windows Live Messenger you can chat with all your friends on Facebook without needing to visit the site. The interface works the same as a regular instant message, so this will feel right at home.
A note on how to set up Facebook chat: If you have already connected Facebook to WLM, you will have to click on the Facebook icon on your contact list to edit the connection, and then make sure you place a check by the chat option. Click Connect with Facebook and it should update your contact list momentarily.
