This document discusses opportunities for improving location-based check-in services like Foursquare by moving to a more passive, permission-based model of check-ins. It suggests checking users in automatically if they spend 15+ minutes at a location and allowing granular sharing permissions. Integrating with social networks like Facebook and connecting to reviews, maps and the businesses' pages are also discussed as ways to keep services relevant against competitors like Google. The document advocates for a more seamless, behind-the-scenes experience for location sharing between friends.
