Actually much like the humans.txt file for sites -- all sites should have a contact.txt file that is modeled after this and has one URL to their address on gmaps.
so you could type into your browser: hardknoxcafe.com/contact.txt and get all the info you needed.
minimal style.
Pretty soon, we'll need some sort of index to manage all of these text files full of useful information. We can connect them together to make it easier to navigate. Let's call these hyperlinks.
