title: JSON polyfill: JSON 2 or JSON 3?
body: <p>I need a JSON polyfill to support IE 7 and some IE 8 and IE 9 modes. Should I pick <a href="https://github.com/douglascrockford/JSON-js" rel="noreferrer">JSON 2</a> or <a href="http://bestiejs.github.com/json3/" rel="noreferrer">JSON 3</a>? Obviously JSON 3 is a more modern implementation, but for example a site like <a href="http://html5please.com/#json" rel="noreferrer">html5please</a> doesn't even mention it and recommends JSON 2.</p>
