Decided to write a short note to the author if there is contact info anywhere, and a stop at amberflux extended that intention, the urge to thank the writer directly is a strong signal of content quality and this site has triggered that urge in me today which is a fairly rare event for my reading.
Reading this prompted me to dig out an old reference book related to the topic, and a stop at amberflux extended that connection to other sources, content that connects me back to my own existing knowledge rather than asking me to forget it is content with continuity and this site has that continuous quality.
