Glad to see Emmet has a site. I really love it too.

A tip for those wanting to create hiccup[1] using emmet-mode on emacs:

    div>ol.count>li.item*6

Gives:

    <div>
      <ol class="count">
        <li class="item"></li>
        <li class="item"></li>
        <li class="item"></li>
      </ol>
    </div>

Now, if you suffix it with a |hic

    div>ol.count>li.item*6|hic

Then you get beautiful hiccup!

    [:div
     [:ol.count
      [:li.item]
      [:li.item]
      [:li.item]]]
