I'm curious if the data harvested from this is skewed to older people, and more "naive" people. Most of my techie friends have uninstalled FB (like me), or rarely interact with it. And my smarter friends just don't interact with that kind of clickbait-y post. I wonder if marketing folks will even notice. Like Google Analytics, which is disproportionately blocked by smarter and more technical people. Marketers cheerfully ignore that, though. Will they even know that they're missing our data? Is the Venn diagram of FB enthusiastic data-donaters and people who don't block GA just a circle? If so, are public policies and corporate marketing strategies going to be designed to cater to them and not us?
