Show HN: Help Those Less Tech Savvy Understand How FB Collects Data

This is a decent way of demonstrating the 'how' of FB data collection. Many people still think of data gathering as read from older click-collection methods and less about active focus data that comes from many minor browser details being monitored. The site could use some tethers to fake (or real) trend and analysis networks to build on that awareness. Also could very much use expansion of their profile results. Good stuff though.
