It’s been 2½ years since I started working on Ember.js. While I’m proud of the code we wrote, I’m even more proud of the community we built.
We have been lucky enough to attract the companies and individuals that are tackling the hardest problems in developing 100% JavaScript web applications; people for whom the only acceptable answer is solid engineering, not piles of hacks.
As we mention in the blog post, Ember.js went through a reboot midway through its life when we realized the thing we were building was not the thing that needed to be built. If you tried Ember.js previously and had a bad experience, I'd really encourage you to give it a whirl again. We've smoothed over the rough surfaces, and now have the documentation and community to help you get started.
If you'd just like to take a peek at what building an Ember.js app is like, I recorded a ~25 minute screencast that takes you soup to nuts:

Lastly, I'd like to express my personal gratitude to everyone that pitched in at the 11th hour to get this release out the door. I couldn't be more proud to call this awesome group of developers my friends.
