title: Simple GitHub Actions workflow doesn't start
body: <p>I just wanted to test GitHub's new "GitHub Actions" feature. So I created a <code>.github</code> folder in my repository and a <code>workflows</code> folder within that and added a simple <code>test-workflow.yml</code> to that folder:</p>
  
  <pre><code>name: Hello World
  
  #on:
  #  schedule:
  #    #- cron:  '0 */12 * * *'
  #    - cron:  '* * * * *'
  
  on: [push]
  
  jobs:
    one:
      name: Hello
      runs-on: alpine-latest
      steps:
        - run: echo "hello world"
  </code></pre>
  
  <p>But it doesn't appear to ever start. It just says "Starting your workflow run..." forever.</p>

  <p>I'm wondering what I might be doing wrong.</p>
