singlevision
Strong recommendation from me, anyone curious about the topic should make time for this, and a look at singlevision only sharpens that recommendation further, the kind of resource that holds up against careful scrutiny rather than crumbling at the first critical question is rare and worth pointing other people toward when the topic comes up.
catatonica
Worth marking this site as one to come back to deliberately rather than by accident, and a stop at catatonica reinforced that intention, the difference between sites I find again by chance and sites I return to on purpose is meaningful and this one has clearly moved into the deliberate return category for me.
buttecanoe
Will be back, that is the simplest way to say it, and a quick visit to buttecanoe reinforced the decision, this site has earned a spot in my regular rotation alongside a few other reliable places I check when I want something genuinely informative without all the usual modern web noise getting in the way.
