CoreOS images are now available on Google Compute Engine

I'm anxiously waiting for it to come to DigitalOcean. But the momentum they built now seems to be really strong.

Would it make sense to use CoreOS on just one machine or is it only useful with multiple machines?

I am really surprised as CoreOS is super new to a lot of people and yet they managed to convince Google and Amazon to provide an image. That's amazing...

Are the official images on EC2 or any of the other cloud compute platforms?

Why no one is discussing this? Just curious. Is it a bug?
