How often have you found yourself interacting online at the dinner table? Our daily routines often incorporate tweeting, facebooking, and the use of other online platforms while in the company of friends.

This example of “social norming” speaks of the gap between interactions online and interactions in everyday life. It also speaks of our inability as designers to imagine less intrusive ways in which digital technologies can be integrated into our lives. (acm.org)
