Listened to This Week In Google 52: Android Goes To War

• Users of social networking websites should be given a clear choice of what they make public and what stays private (by default)
• However, there are benefits to making things public, e.g. your real-time location may give you coupons to a bakery you are in.  Also, people may share things with you they might not otherwise do, by knowing what you've made public--mutual benefit because of openness 
• The problem is when some social networking websites prevent access to data (via APIs) that people have already indicated as public.  This data then cannot be mined by other organizations or analyzed for societal benefit
• With data showing that more Android phone are being activated per month than iPhones, and the number of Android apps becoming available, iPhones and their apps may be relegated to a niche market, like computers with Mac OS, in the near future.  The $99 USD to become a iPhone developer and the need to do development on a Mac hampers innovation (as some of the brightest developers may simply choose not to be limited by Apple)
