"Activity streams are turning social services into a flow of updates, filtered through people. Mobility is introducing new types of social objects that change the nature of the update streams both into something more frequent and more ambient, but also more vulnerable to noise.

I’ll demonstrate how the concepts of social objects and social peripheral vision can be applied to make sense of this shift in the locus of innovation on the social Web, and share some personal war stories along the way." – jyri
