I absolutely agree that comparing actual apps is a very useful point of comparison.

Ember itself is actually relatively new. The fact that Ember inherited some of its runtime semantics from SproutCore might give the mistaken impression that there is shared code. Everything, including Ember's runtime, was rewritten from the ground up for Ember, and it's only with the release of Ember 0.9 that I consider the APIs and codebase stable.

Some companies, like ZenDesk, hopped onboard earlier in 2011, while the codebase and APIs were still undergoing a lot of churn, and helped flesh things out. That said, when taking the scope of Ember into consideration, Ember's adoption curve is behind's Backbone's, so it's not surprising that there are many more impressive Backbone apps in the wild.

We're proud of many of the apps that people are building with Ember today, and as the year progresses, hope to compare favorably to Backbone's impressive list.

I'm very much looking forward to seeing them. The more different takes on JS-heavy apps the better.

I'm about to crash, but would you mind expanding on what you've written here -- "rewritten from the ground up", and so on -- in relation to earlier posts like this one:

http://blog.sproutcore.com/sproutcore-amber-a-report-by-yehu...

... which describe what I've always understood to be the heart of Ember as an iteration on the core SproutCore internals. Does that blog post no longer describe what ended up happening to Project Amber?

Can't we all just get along...

I've been working with Backbone intensively since V0.1, and though I've very scarcely looked at ember, I've been following the heated discussions on both sides. Personally, I think it's damaging to both your publicizing efforts.

Perhaps what would be more beneficial is a more complex hello world app than the todo list. One that expresses the flexibility of Backbone's minimalism, along with the larger out-of-the-box functionality of Ember. I'm personally in the Backbone camp, but it would be easier to let the user decide what is best for him/her.

On the contrary, I've found the discourse between Jeremy and Yehuda vigorous, respectful, and edifying. In my opinion, these are the best kinds of technical discussions; they are like a rock tumbler that wears away at our solutions until we're left with shiny best practices--and can move on to the next big problem to solve.

Actually, it probably helps both publicizing efforts. As the Internet-wide debate becomes "Backbone vs Ember," it puts the focus on those two techs and leaves other competitors out of the conversation.
