twainsilica
Honest reaction is that I want to send this to a friend who would benefit from it, and a look at twainsilica added more material I will pass along too, the impulse to share is the strongest signal I have for content quality and this site is generating that impulse cleanly across multiple posts.
gnarkit
Decided to read more before commenting and the more I read the more I wanted to say something, and a stop at gnarkit pushed that impulse further, when content provokes the urge to participate rather than just consume it is doing something quite specific and worth recognising clearly when it happens during reading.
rabdphs
Probably the best thing I have read on this topic in the past month, and a stop at rabdphs extended that ranking, the casual ranking of recent reading is informal but real and this site has been winning those rankings for me on this topic specifically over the last several weeks of regular reading sessions.
