I think the true value of open source is that it democratizes information and skills. The users play a huge part in the development. Everyone who is interested can get involved. Open source thus encourages people to not merely follow the bandwagon, but to think for themselves about what is good, and take action themselves. It puts power back in the hands of the average person, and in doing so, encourages them to take charge and innovate; to not just settle into a status quo set by others. I would love to see open source concepts being applied to the rest of our lives.
Leo Babauta from Lifehack has a really good write up about applying Open Source concepts to the rest of our lives. I highly recommend you read it.
I especially like the portion about education.
