A traditional blog post can be thought of as residing in a network, with webpages linking to and from it. However, if one were to naively consider every incoming and outgoing link to this webpage, it can become a bit chaotic. This series is my humble attempt to manually curate a network (a 'roadmap') with interesting content from the internet along with my own commentary as needed. This will hopefully serve as a compass to those who wish to navigate its treacherous seas.
