Killing dreams

Many personal apps and gadgets have the effect, or at least the intended effect, of formalizing informal activities. Once you strap on a Fitbit, you transform what might have been a pleasant walk in the park into a program of physical therapy. A passing observation that once might have earned a few fleeting smiles or shrugs before disappearing into the ether is now, thanks to the distribution systems of Facebook and Twitter, encapsulated as a product and subjected to formal measurement; every remark gets its own Nielsen rating.
