People tend to refresh the same feeds/groups/sites repeatedly, unthinkingly. Each of those has biases depending on the people who post there. Something useful to interrupt the unthinking refresh cycle would be an app or extension that analyzes group sentiments and occasionally signals "You've visited this site 3 times today. Would you like to try one of the following to see some different viewpoints on the same topics?" Probably not possible without privacy issues, but if opinions are already being tracked that way for advertising and surveillance purposes anyway, we could get some value out of it...
