If SwipeGood can help pursuade people to donate more to charities then good for them, but it's not for me. I already donate to a few charities on a monthly basis, and am open to making one-off donations now and then to others (and do that fairly often). I donate based on how much money I'm willing to not have - i.e. the most I am "able" to afford without it impacting on my other monetary plans. If I used SwipeGood then it would either donate more (which I don't want, and if I did, I would chose to donate more right now) or less (and -5% for SwipeGood), so it would be a lose/lose.
