Another thing that would really help Ember's popularity are screencasts, something like egghead.io, where you'd show off some more advanced stuff. I know that they'd probably be a lot of work to make and to keep up to date, but they are pretty invaluable for getting users up to speed. And the time spent doing these is an investment, you guys would spend less time answering questions and you'd probably have more committers which also saves time (maybe).
Edit: Now that I think about it, aren't DHH's Rails screencasts considered one of the reasons why Rails got as popular as it did?
Thanks, I'm aware of those. Nevertheless, three paid screencasts by third parties aimed mostly at beginners are not the same as a long-term effort made by the Ember team to make these videos and keep them up to date. IIRC, the Rails team was putting out like a video every month or so. This might be one of the things that made people aware of Rails since even non-Rails devs were aware of these videos and eventually, some of them were tempted to check out what the commotion was all about and eventually switched. If you show people how much one can do with Ember in say 10 minutes, more people will be interested in the framework.
Edit: Now that I'm rereading my post, it sounds really entitled and arrogant when it was not supposed to. It's more like "if I were on the Ember team, here's what I'd try to do".
What's needed, and I'm sure it's just a matter of time, is an embercasts.com in the style of railscasts.com. I think Ryan's way too busy to double his workload, so the opportunity is there for someone else to take up this banner.
