Facebook isn't being shy about rolling out its Timeline interface to as many of the corners of its site as it can. In addition to the rumored addition of the Timeline to Brand Pages, the social network is also adding Timeline features to Facebook Groups. The most obvious change is the new full-width top image, though if the administrator doesn't set a lead image it defaults to a collage of the profile images from group members. There are also clearer sections for group topics, links, members, and events. The new topic prompts, "What should people post in this group?" is apparently designed to make it less likely that groups will be filled up with the kind of chatter than can result in annoying notifications.
The features are available now to all users.
