UseFun

This is a new mini wiki about doing things useful for humanity, while having fun.

The inspiration comes from the scientific "Doomsday Clock" ( http://www.thebulletin.org/ and http://www.thebulletin.org/minutes-to-midnight/ ) that clearly shows that not enough people care about our future. The main reason is that people think they can't have fun while doing useful things (it is easily shown by the number of hours people spent each day watching TV).

We will have two main categories:
 * Tips for adding fun to existing useful activities
 * List of known fun and useful activities, including meetings with other "fun and useful" people.
