I own CAD books 1 and 2. I quite enjoyed CAD, a good few years ago. Then, the melodramatic storylines kicked in like hell (Lucas' psycho girlfriend, Lilah's miscarriage, Ethan locked in a box...) and the whole thing started sucking hard. I still occasionally read the latest few, and it hasn't improved in a while. Only costs me a little time to read it, but overall it's stopped being entertaining. That and I've known for a long time that Tim Buckley, as an individual, is extremely unlikeable.
Regarding Yahtzee's "review" - this is what Yahtzee does to games, he's just doing it to webcomics instead for a week. He's right on every count, as he is every week, but I'm still reading some utter crap and some awesome stuff.
In summary: CAD has gone downhill badly, Yahtzee is right on every count, but that doesn't mean I follow his opinion blindly (example: he's right about SSBB being a particle-effect shitstorm, and the initial gameplay without unlocked characters being "ehhhh", but I'm playing it like mad, because like he said, I already knew I was going to like it, and I was right!)
Reading between the lines, this has generated a lot of noise (17 pages and counting), but there's very little "flaming" as some people seem to think. There's some "CAD isn't that bad" and "CAD is terrible and so is everyone that reads it", but very little direct flaming. Congrats to The Escapist forums for keeping the place moderately civil.
