@Maddus Mattus:You make a good point but I suspect Bll G is wise enough to appreciate that it is a two stage process.  Stage 1 is simply encouraging people to give, that is what 'giving Tuesday' is about (as far as I can tell).  Once the resources (time/goods/money or whatever) are available stage 2 is about making effective use of them - this surely has to encompass the value proposition that you talk about .
