I realize that a couple of the blogs mentioned I wouldn't recommend to the casual visiter to this site. I've had specific reservations - rather deep reservations about some of the stuff posted on some of the sites on my list. I've added a couple too. In case you didn't know, one of the ancestors of my part of the Rinzai school, Soen Shaku, spent a significant portion of time with Theravadin monks; I definitely feel an affinity to a lot of what they put forth (though not everything in all cases). Soen Shaku, contrary to narratives of Japanese Zen adepts whose heirs and teachers reached the West, namely Nyogen Senzaki and Ryobo-an Sokatsu were scandal-free.
I think it's better to not promote those questionable blogs in my own way. In two cases especially it appeared that what was being promoted was so at variance with Zen Buddhism as I've apprehended it that it's better not to promote it as a blog I recommend, even if listing it only as "one I follow." Barry Ritholtz is a more reliable Zen guide, even if he never blogs about Zen (and I recommend his writings, even when I disagree with them if you're tasked with managing your retirement). I will probably have a more in-depth post on it later, but to make a long story short (for now), there's a lot of people that want to "make Zen better," and they're not doing sentient beings many favors in doing so.
