      you mention social media as a form of mobility.  I can't claim to have read all the great work that's out there on agglomeration economies and transportation.  HOWEVER, David Engwicht's _Reclaiming Our Cities and Towns: Better Living Through Less Traffic_, has an incredibly great discussion and a diagram on how cities were created to facilitate (all forms of) exchange, and the impact of devoting space to auto traffic at the expense of other modes reduces the spaces made available to facilitate exchange.

      Social media is another form of exchange.  It facilitates interaction.  But like induced demand with adding roadway lanes, social media induces "time demand".  In the US, it is argued that part of the decline in car purchasing is because of the increased use of social media within younger demographics.

      Subject: [NewMobilityCafe] "Travel-Time Budget" for Twitter et al


      Remember Yacov Zahavi of the World Bank and famous his "Travel-Time Budget"? In a nutshell it read like this: The research showed that…

      a) most of the world spends about an hour a day in travel
      b) most commutes are under half an hour, and
      c) Families spend about 12-15% of their disposable income for mobility.

      What's the point in our present discussion context?  Well, it's a question really.
      As we talk about time spent/misspent with things that on the surface are supposed (at least in part) to be useful -- such as Twitter, Facebook, et al -- do we in fact have, individually and as groups, our own Time Budget for these kinds of "information commuting" activities.
      From a personal point of view I may be protected because I put a high value (?!) on my personal time, to which I can add a pretty low threshold for wasting my time.  So I think personally I am OK.  Thus far.
      But back to Zahavi, which is far more interesting than my personal case: There must be analysts who are working with this, and it would be interesting to know a bit more about them.  It can be argued that the social media are themselves a form of mobility.
      In the meantime I muddle on and post this reflection to Facebook, Twitter and one or two other hopefully somewhat efficient places..
