Have you considered how farmers are communicating socially outside of our United States? Of course, many are doing so through Facebook, Twitter, etc. just like farmers here. But there are also a number of social networks being developed. Here’s one that came to my attention via Twitter last night. It’s SojaBook.
SojaBook is the social network that connects you with area people in the countryside.
I don’t have much more information about it except that it’s structured so that you can use it in a large number of languages and that’s a great feature. If you join let me know what you think.
