A Smarter Lizard Gecko is no ordinary lizard. It's as if your ordinary little creepy, scaly thing that makes annoying noises and climbs walls suddenly grew opposable thumbs and an enlarged frontal lobe, invented fire, the wheel and language and started a glorious civilization overnight, and managed to do that without having to fight gruesome wars or oppress the better part of its fellow lizards.
Gecko is an evolutionary leap in browser technology.
It just rewrote the rules without breaking the old ones. Using Gecko feels like living in a new, better World Order that didn't involve killing off the ruling class. It's like being politically correct and still thinking Tarantino films are funny. One of the things I have said on HTML with Style is that you no longer need to break the spec to get new features. The stuff the W3C has produced in the past couple of years has more functionality than any browser currently on the market can dream of.
