Anyone have some good links/citations on the consumer surplus of Google? How much value do we get as users? Considering the value of time, past consumer surplus is especially valuable now. Sure, there are systematic flaws causing SEO to ruin the information provided: but it isn't clear what Google can do to fight the emergent system. I'm not sure that Bing/DDG are any better. I use search (DDG web, Google/Apple maps, YouTube) all the time and I am regularly given results that are extremely valuable to me (and mostly only directly cost me a small amount of my time some of my time e.g. YouTube adverts). Blaming SEO on Google seems thoughtless to me. Google appears to be the victims of human cybersystems as much as we are.
