Mars colonization is kind of interesting initiative. It is fascinating to read technical features for securing the life and Mars human base. What about human leisure?
The very first item is connection to the earth friends of martian people. How would they connect? If it will be provided via space discovering corporation, the whole communication will be published to the mass media. And if will be something private only for two people? Will it be read by the third side? I think, it will, so the longer it least, the faster people on Mars will lose their friends, as they can not speak about something special only for friends.
