Sorry - I meant to add an explanation and got distracted. Thanks for doing it for me :)

If anyone reads those links and still has a question I haven't answered there, I'd be happy to take a crack at it. It's a tricky situation because all of these things are true:

(1) it's the biggest technological development in a long time;

(2) there's way too much material about it, a lot of which is mediocre;

(3) every user has a different threshold for what feels like 'too much' about it on HN.
