Tiny House Village Network

This looks pretty interesting. Unfortunately, to join, you have to pay a "donation" of $10. I think that it's reasonable to charge a fee for the hosting of a network, but I'm also unsure as to what I will receive in return. Is it simply access to communication with other people in the network? How do I know if I will get more than what I can access on facebook?
Should I set up a network for Canadian tiny-homers?
