re: Can Someone Explain All the Different Things Google Does...

They're breaking away from WebKit as a way of destroying or severely weakening Apple's place in the mobile web ecosystem. WebKit is still Apple's property even though its used right now by everyone. Blink is ani-consumer and pro-Google. At least it is if you are anyone but Google.

They bought Motorola in response to bloat ware, software skins, and the unintended ways that Amazon and now Facebook are taking advantage of Android. Also they feel Samsung got to big thanks in large part to Android. They want no one company holding too much sway over what they do.

They are into driverless cars and augmented reality/wearable tech as a way of staking claims to still new ways of integrating search info/ad clicks into your life. If Google develops the architecture a driverless car uses to operate, it's the same principle behind developing Android. It gives them a window into your habits and an easy platform to serve you ads. Same w/wearable tech.

Google wants to be at the top of the heap. It doesn't care if you're Apple, MSFT, Samsung, Facebook or even Mozilla. It's future depends on its ability to collect info about you in order to deliver you advertising info.

Developing its own mobile and tablet products through Motorola enables it, as does forking WebKit and turning towards Blink. Some of its decisions are good ideas (Motorola will help give Android users a better UI experience). But some are designed to crush their competition (Blink) and in the short term it will make the mobile web a less smooth, more chaotic experience.
