Growth Spurt

So two blogs below, I hypothetically wondered what the difference between a community garden and a cultivated one was. Yes, there is something aesthetically different, that is perhaps most obvious. But it must also have something to do with how it comes to look that way. One could say, people make it different. Yes, but people could also make something completely different from a community garden, a whole industry is devoted to landscapers. What sorts of people community garden, what makes it different from a farm, or your backyard? Perhaps it's more about community that it is about gardening?
