I think probably things along the lines of what's been called the 'cozy web': networks of smaller groups that don't publish to or expect responses from effectively the entire internet as a whole. (This kind of thing has always existed, it's basically the group chat with your friends but perhaps slightly bigger, but I think there's a bit of a trend of focusing on it more because of the feeling that the twitter/facebook attention and feed model is bad for your mental health. I've always felt the twitter model especially was pretty cursed so I'm glad there's some agreement building there).
