There are some other issues for users trying to follow along. I hit my next snag from moment.js not being imported, and not having the filters domain, amFromUnix and amTimeAgo not being found. I see you addressed these points later on in your post notes, kind of as an "excercise left for the user".
After that point, I just read the article and stopped trying to follow along. Perhaps it wasn't your intent to make a step-by-step type article, but I'm just sharing the experience I had trying to go along one step at a time. I appreciated the article, especially because right now we're starved for Angular 2 content, and there's not a lot out there yet.
Fails for me pretty early on:<p>ng set defaults.styleExt scss<p>Could not start watchman; falling back to NodeWatcher for file system events.

TypeError: Cannot read property 'serialize' of undefined<p>I installed watchman and received the same error<p>Looks like this has been reported elsewhere: <a href="https://github.com/angular/angular-cli/issues/1905" rel="nofollow">https://github.com/angular/angular-cli/issues/1905</a>
I built a Hacker News client with Angular 2 (<a href="https://angular2-hn.firebaseapp.com" rel="nofollow">https://angular2-hn.firebaseapp.com</a>) and shared it here a short while ago (<a href="https://news.ycombinator.com/item?id=12438119" rel="nofollow">https://news.ycombinator.com/item?id=12438119</a>). Got some very useful feedback and thought it would be nice to write a post on how I built it. I go through building the entire app step by step from scratch solving each problem along the way.<p>As always, I hope you find it useful and would appreciate any feedback.
Just a minor point, but your first stories.component.html snippet doesn't include {{i}}, so the way it renders in the browser is different than your screenshot
