"Digital giving" capitalizes on technology and younger givers, and helps charities know whom to thank (unlike change in a collection box).
"Fewer people are donating money to charity these days, and they are giving less. Using official surveys that reflect ordinary personal giving, the Charities Aid Foundation (CAF) has calculated that donations are at their lowest in real terms since at least 2004-05, when the data began. The sluggish economy probably has something to do with it. But another explanation is that charity has failed to keep up with technological change. Richard Harrison, head of research at CAF, says the charitable sector is stuck in the 1990s, or even the 1980s." -- the Economist
