I found myself on a commuter train on the way to 2gether08 on Thursday morning.

Literally hundreds of, most probably very bright, people around me were heads down, buried away in Sudoku puzzles or reading the Metro - occaisionally checking their phones or Blackberry's.

What if we could find some way of harnessing that cognitive surplus - and providing volunteering/pro-social crowd-sourcing opportunities that commuters could dip into at five-minutes-to-nine, just before they got stuck into their nine-till-five?

Just a thought...
