title: Count of subscribers to a GitHub issue?
body: <p>GitHub allows me to subscribe to issues but does the GitHub API allow me to determine the count of subscribers to an issue?</p>
  
  <p>My thinking is that if the subscriber count were exposed it could be a form of voting for an issue. Right now, you often see people "voting" for issues by adding a "+1" or similar comment, which can clutter up an issue.</p>
  
  <p>(There have been calls for an <a href="https://github.com/isaacs/github/issues/9" rel="noreferrer">explicit <code>+1</code> feature for issues that isn't a comment</a> and <a href="https://github.com/ryanflorence/github-plusone-extension" rel="noreferrer">browser extensions</a> developed to declutter issues.)</p>
  
  <p>I checked <a href="https://developer.github.com/v3/issues/" rel="noreferrer">https://developer.github.com/v3/issues/</a> and it doesn't seem like determining the count of subscribers to an issue is currently possible, unfortunately.</p>
