@Ian2: I don't agree with Bill Gates. You can't just give away stuff and think that will help. We've been trying to give away stuff for a better world for 50 years now, it's not helping.
When you give away something for nothing, people value it at nothing. Only way forward is to trade with them. Let them become self sufficient, instead of dependent on handouts.
Black Friday and Cyber Monday are helping the world become a better place more than Giving Tuesday, IMO.
