Facebook friend grouping on the way

We know that Facebook is moving at lighting speed to stay 20 steps ahead of the social networking game. Here‘s a couple of other features that Facebook has in the works to do just that:
The ability to sort your friends and organize them into groups is an upcoming feature that nicely aligns with the objectives and functionality of Facebook. This will allow you to better determine who sees what kind of content, and simply offers more privacy options within your personal networks.
Another upcoming feature is the ability to read email messages in digest form, which means you can receive one single email with all of your notifications, sent to you on a daily basis. These are small tweaks, but good tweaks nonetheless. MySpace, Xing and Friendster have been modifying their profile pages for the better as well.
