Are there technical solutions here? The client-server model of the WWW seems to tilt in favor of consolidation. What about something more akin to database replication for sharing information? Data moving around asynchronously, viewed at the users leisure, and synchronous actions are only needed sometimes (e.g. for buying things). Right now, a lot of synchronous things happen, requiring users' action and attention for little reason (but encouraged by the client/server model because you need to make a request). It would certainly change things. "Engagement" might be harder to measure and monetize, so it might force us toward something more like micropayments. But micropayments might be more possible in such an environment as well. With little money on the line, it's easy to update a database record and move the real money around later (if that's even required -- you could imagine digital IOU records acting like currency). And more importantly, I think it would reduce the need of companies like facebook and other consolidating forces (though perhaps not google search).
