Features Of The New Facebook Groups

Group Notifications
One of the most significant features that Facebook groups used to have was the ability for administrators to message members of the group directly. Now Facebook has made it so that all messages (or any other objects) posted to the wall in within groups will generate notifications. These notifications drive users back to the group, however users can also opt-out of these notifications by clicking on the “Edit Notifications”.
Group Chat
Group chat is probably one of the most significant features of the new Facebook Groups product. All members of a group have the ability to engage in a single chat window. The one downside of this is that it group chat rooms can become pretty noisy. This is a major upgrade however in that Facebook now has “chat rooms”, something that the classic AOL was infamous more. Don’t call it that though! The primary difference between a traditional chat system and the Facebook group chat system is that unless your group is “Secret” (and undiscoverable in search), your real identity is being used.
In AOL Chat, IRC, and other open chat platforms, users would use their aliases as a way to mask their real identity.
Docs
One other feature of Facebook’s new groups product is the ability to post “Docs”: basic text documents with a minor amount of markup available (bold, italics, and lists). Documents also have a revision history which users can navigate back through. While this is no Google Docs product in terms of robustness, it’s definitely a useful feature.
Groups Have Become An Integral Component Of Facebook
Facebook groups are now an integral component of the entire Facebook experience. Between group chat, docs, and an eventual groups developer platform, Facebook is aiming to become a more significant communications and collaboration platform.
