PCWorld is reporting that Facebook has added an instant messaging service, though it is in limited release so you may not see it on your profile page. Facebook Chat is an instant messaging service that is tied to your facebook user name. According to the official Facebook blog "We'll be rolling this out slowly going forward, but fairly soon you'll notice our new Chat bar at the bottom of your browser—no installation or assembly required. From this bar you can view your list of online friends and open conversations with any or all of them." Chat is certainly not new but the feature is definitely a natural fit for the social networking site, it will definitely increase the sites stickyness!
