> no JavaScript

Not to knock an otherwise nice site (CTRL & + improves readability for me personally, though), but:

    (function(d, s, id) {
      var js, fjs = d.getElementsByTagName(s)[0];
      if (d.getElementById(id)) return;
      js = d.createElement(s); js.id = id;
      js.src = 'https://connect.facebook.net/en_US/sdk.js#blahblahblah';
      fjs.parentNode.insertBefore(js, fjs);
    }(document, 'script', 'facebook-jssdk'));

AFAIK, even for sites that want to feed the monster, that's unnecessary:
