Just as previously reported, Facebook has begun rolling out their IM client on some selected networks. This was the only available information since the complete roll out schedule has not been made public. it is to be released to limited networks first for load testing and bug-hunting, and then rolled out to broader networks.
The new chat bar appears at the bottom of every page and cannot be removed. The client has all the regular functionalities that you would expect such as the ability to show yourself as offline and lets you know who is available for chatting.
The integration is very well done and should prove to be a great addition to Facebook. I know that it will give a good reason to many people for leaving a browser with Facebook open all the time. You can find a full post about the features with screenshots here if you can’t wait to try if for yourself. You can “pop-out” the chat windows to allow many chats at the same time and a better visibility and the status window shows your friends letting you know who is active or not.
Mini-feed items will also appear directly in your chat windows for the person you are chatting with if they are related. So if you are chatting with someone who does something on your profile, you get instantly notified.
I hope the networks I am in get this very anticipated IM Client rolled-out because I am really anxious to try it out. Not that I have that much chatting to do, but I like the technical integration that they have made and I want to try it out even more for myself.
