Among the usual kinds of pages that this website hosts there are many documents that we're calling "linktopics" because they are so richly endowed with embedded links referring to other content selectively reused. Linktopics live in the Internet while riding referentially above it. They serve as selective doorways into the rich content of the Interent. It's the web looking at itself from a higher (or essentially HIERarchical) vantage point with commentary, review, and analysis. Over time the network of evolving topics here will dynamically grow and coalesce into a hierarchy based on their content. For now, a modest hierarchy of such topics will start the collection.
