title: Public Google Cloud Pub/Sub Topics?
body: <p>I'd like to play around with <a href="https://cloud.google.com/pubsub" rel="noreferrer">Google Cloud Pub/Sub</a> and processing messages in <a href="https://cloud.google.com/dataflow" rel="noreferrer">Dataflow</a>. Are there any public data feeds in Pub/Sub that I can use to get started?</p>
  
  <p>In the Dataflow <a href="https://cloud.google.com/dataflow/examples/wordcount-example#minimalwordcount" rel="noreferrer">WordCount</a> example, input is read from a file in <a href="https://cloud.google.com/storage/" rel="noreferrer">Cloud Storage</a>, <code>gs://dataflow-samples/shakespeare/kinglear.txt</code>. It seems that <code>dataflow-samples</code> is accessible to all projects, which is very convenient for getting started. Is there anything similar for Pub/Sub?</p>
