usage.hbs

Angular

<multi-avatar data-facebook-id="717976707"/>
<multi-avatar data-github-username="jwo"/>
<multi-avatar data-email="jesse@rubyoffrails.com"/>


Ember

{{x-avatar service="github" user="rpflorence" width=50 height=50}}
{{x-avatar service="facebook" user="717976707"}}
{{x-avatar user="ryanflorence@example.com"}}

@rpflorence I'm pretty sure I'm the one that screwed you here. I tweeted this as a "comparison" of ember and angular. https://mobile.twitter.com/polotek/status/387601840516259841

I didn't read the gist description and screwed up the context for everybody. Sorry.
