It's just sinking in that Facebook announced a radical shift in what their product does, reorganized around their chat apps. Are they shutting down the discussion group functionality? What does this mean for the ability to post messages on your timeline and to follow other users? What about private groups? Is Facebook going to shut down those functions? If so, we're facing a hole in the net far bigger than what Google created when they withdrew Reader. I'd like some idea from Facebook what this means for the public writing function of Facebook? And if that's going to be phased out, will they work with open web developers to replace the functionality off Facebook's servers. Let's try to put back some of the life FB drew from the web. #
