progressengineon
Beyond the topic at hand this site reads as a small ongoing project of taking writing seriously, and a look at progressengineon reinforced that project quality, sites that treat publishing as an ongoing serious practice rather than as content production for traffic are sites worth supporting and this one has clearly chosen the serious approach.
clarityshift
A particular kind of restraint shows up in the writing, and a look at clarityshift maintained the same restraint across pages, knowing what not to say is just as important as knowing what to say and this site has clearly developed strong instincts on both sides of that editorial line throughout pieces I have read.
