◊ Fail gracefully
When an interaction relies on shared data, provide a
reasonable fallback if the data is no longer available.
◊ Don’t build bubbles
Let people choose between tailored interactions
and the collective (generic) experience.
◊ Share your toys
Don’t be only a consumer of personal data,
give back to the ecosystem.
◊ Provide an exit
People should be able to share, but also to pack up and leave.
