There are many parts of Maslow's hierarchy. Curing malaria allows more people at the low end of the hierarchy move up. Obviously, this is incredibly worthy. I don't know about Facebook for dogs, but there is an AirBnB for dogs called http://dogvacay.com http://dogvacay.com which lets you board dogs in other people's homes. This allows dog owners more freedom, and allows people without dogs to hang with dogs for a few days a week. Since pet ownership reduces stress and increases people's happiness, "dumb ideas" like this move people like me slightly higher in Maslow's hierarchy. Long story short, the OP should pick better "useless" examples.
