I have been thinking about this a ton in the last few days since I saw this. I've been thinking about how before we became so interconnected people cared so much more about their local communities. You couldn't just go online and find people to talk to. So you had to be a good steward of your local community or risk being ostricized or exiled. You had to produce value for your community to have any status.
And the shopping cart phenomonon just so clearly puts that on display. Just wanted to let you know that you really planted something in this Internet stranger and I appreciate you for it.
