Facebook’s Onavo Gives Social-Media Firm Inside Peek at Rivals’ Users
A comment on the WSJ brings up an interesting point—if Zuckerberg were to run for president, would he have access to this information? What else could he have access to?Given the amount of data Facebook has about everybody, I find that possibility worrisome.  It seems obvious that a campaign strategist could segment individual states, regions and cities. They could target people based on likes and interests. They could get very granular with messaging—advertisers can do this through Facebook right now.But what other information could be used that advertisers don't have access to? Application usage, website visits, WhatsApp message keywords?
