<!-- formatting fun #1: tables! -->

<!-- use whitespace to mimic the layout you want. leave off optional end tags for readability -->

<table>

  <thead>
      <tr><th>Left to right            <th>Right to left 
  <tbody>

<!-- formatting fun #1.5: lists! -->

<h3>Reasons I love not closing all my tags:</h3>

<ul>
  <li>Better readability
      <ul>
      <li>Less visual noise
      <li>Angle brackets are gross
      <li>Semantic indentation (what??)
      </ul>
  <li>Better maintainability
  <li>Feels good, man.
</ul>

<!-- 
Mostly I don't close my <li>s. As shown above, a table can look fantastic without end tags. And also, in a string of <p>'s I won't close those either; feels a lot like the English grammar convention of..

"opening a quote and 
"splitting it over some paragraphs."

But then again I'm keen on generating markup via jade/slim/markdown as my fingers are quite tired of typing (and my eyes are tired of looking at) angle brackets. :)
