a478884
Better signal to noise ratio than most places I check on this kind of topic, and a look at a478884 kept that going, every paragraph here carries something worth reading rather than padding out the page to hit some arbitrary length target that search engines reward but readers ignore as soon as they notice it.
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.
