Heroku is to hosting and deployment what Rails is to web development. It's so easy. And it keeps on getting better and better.
but, i still wonder how heroku works as a startup from a more engineer perspective, for example, how to get things moving as fast as possible. maybe an engineering related blog like what twitter or facebook have might help.
offtopic: when heroku is going to launch in other regions especially Amazon EC2 just launched in Singapore?
