One of the most significant social and economic trends that has emerged from technology entrepreneurs in 2011 is collaborative consumption.
For many city-dwellers, there's a huge disconnect between the number of friends we have on Facebook, and the number of friends we have in our neighborhood.
Yet when you really need a friend, it is at least helpful and sometimes critical that that person lives nearby.
Blockboard is a hyperlocal startup on a mission to do something about that problem, first in San Francisco, and then in other cities across the country.
When you download this free iPhone app, it recognizes your location via GPS and suggests which of 38 separate neighborhoods that make up this 49- square-mile city where over 800,000 of us call home might be yours.
“Neighborhoods are more emotional than physical, in many ways,” notes co-founder Stephen Hood. “So although Blockboard will suggest which neighborhood we think is yours, it’s up to you to choose.”
