Bloat comes from people spanning everything instead of just the differences:
Code:
<p><span class="bloated-normal">This is Span<\span> <span class"underscore">Abuse</span> <span class="bloated-normal">at it's worse.</span></p>
Code:
<p class="normal">This is Span done <span class"underscore">nicer</span> more normally.</p>
