Really excellent points. Also it's worth considering that most of the people providing these solutions are not equipped with the expertise or experience to tackle 'third world problems' like floods or infant mortality. No amount of AngularJS or Clojure can solve these issues. However photo sharing is a domain that is approachable and there are obvious financial incentives to do so.
