This is a very brief post announcing a fascinating discovery. It appears to be possible to use the cosine similarity approach powering explore2.marginalia.nu as a substitute for the link graph in an eigenvector-based ranking algorithm (i.e. PageRank). The original PageRank algorithm can be conceptualized as a simulation of where a random visitor would end up if they randomly clicked links on websites. With this model in mind, the modification replaces the link-clicking with using explore2 for navigation.
