Attribution and acknowledgement of sourcing are not only the right thing to do, the honorable thing to do, they are the very strands in the thing we call the web. They are what connect it all together. They help to explain how I got here from there and why. They also help you navigate back down that thread and, hopefully, onto other places filled with wonder, curiosity and delight.
