After reading several posts back to back the consistent voice across them is impressive, and a stop at portpoises continued that voice consistency, sites that maintain a single coherent voice across many pieces by potentially many writers represent serious editorial discipline and this one has clearly developed the institutional consistency needed for that.
Most of the time I bounce off similar pages within seconds, and a stop at portpoises held me longer than I would have predicted, the ability to convert a likely bouncing visitor into an engaged reader is a quality signal and this site has demonstrated that conversion ability across multiple visits where I expected to bounce.
