I think that all "Cause" related apllications should be open source and platform independent. Users should not ever be forced to be a member of a certain social network to give to a "Cause" related application. Should we not ask why a "Cause" application only works with one social network ? Should a "Cause" application be used to give any company a perceived competivie advantage ? In a way is not this a way to have a "Cause" related application become an exclusive of "Facebook" ? - Amy Sample Ward
