One major issue I found while starting with Ember is that the framework is changing so rapidly that even resources that are only a few months old might be deprecated. I watched countless videos online and read a ton of blog posts, but they didn’t really help, especially because none of them were using Ember CLI.
Ultimately, I found that the single greatest resource is this forum, coupled with attempting to create your own project. Some of the replies that I have received on this forum were 100% crucial to my understanding of Ember. I also found that working on my own project raised new questions for me to think over, which further increased my understanding as I slowly worked through these problems.
That being said, maybe you will find screencasts and videos that you find helpful. At the very least, I found that even outdated tutorials still got me thinking about the basics like Ember conventions and Ember Data, so they can still be useful in many ways.
