This month's Net Tuesday will be on "crisis response" and social media.

Recent crises — whether caused by nature (like Haiti or Katrina) or by humans (like the London subway bombings or PA budget cuts for arts and culture) — have been met by a new type of response virtually unavailable just a decade ago.
