Really good animations, really good points, but I don't recall seeing any <i>concrete</i> suggestions in any of these.<p>Are they just high-profile, high-quality rants, hoping to get <i>others</i> to come up with changes? Or is there something more concrete backing these that isn't disseminated with them, preventing their (really good?) ideas from being implemented?<p>I've only seen a few, but are others more <i>useful</i>? They're all <i>interesting</i>, but those aren't the same thing.
