title: What's the best way to collect user testimonials on GitHub?
body: <p>If I want to allow users to submit testimonials about a software project hosted on GitHub, what is the best way to collect user testimonials?  </p>
  
  <p>Ideas:</p>
  
  <ol>
  <li><p>Open an issue, and link to the issue, letting users post their testimonial as a comment.</p></li>
  <li><p>Create a <code>testimonials.md</code>, and let users contribute testimonials as pull requests.  </p></li>
  <li><p>Do something through the Wiki, which also involves pull requests.</p></li>
  </ol>
  
  <p>I'm favouring 1.  What's the best method?  Surely someone else has done this already.</p>
