This is of course well meant and I think it is good to remind people, that there is no need to use Ember Data in Ember, but I have one objection:
The example only fetches records from the API and never creates, updates or deletes any. This is actually something that can easily be achieved with Ember Data today and in fact it is the one thing that is well documented.
The right page should be: https://github.com/eviltrout/emberreddit
The link to the github project on the parent page is correct though.
