The map
Everything, and what it connects to.
A hundred and ninety-six pages and every link between them. Nothing here is drawn for effect: if two nodes are joined, one of those pages really does reference the other. Scroll to zoom, drag to pan, click a node to pull it into focus, click it again to open it.
The big bright nodes are the index pages, which everything links back to. The long gold chain is the series, each post pointing at the next. The dense knots are where a topic got written about from several directions at once, and those knots are usually the parts I understood worst at the time and kept coming back to.
