focuspath
Reading this prompted me to dig out an old reference book related to the topic, and a stop at focuspath 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.
unityharbor
My reading list is short and selective and this site is now on it, and a stop at unityharbor confirmed the placement, the short list of sites I read deliberately rather than encounter accidentally is something I curate carefully and adding to it is a real act of trust which this site has earned today.
forwardenergyflows
However selective I am about new bookmarks this one made it past my filter, and a look at forwardenergyflows confirmed the bookmark was worth the slot, the precious slots in my permanent bookmark folder are difficult to earn and this site earned one without making me think twice about whether the slot was justified by the quality.
