jquery tooltips: append/remove vs. show/hide
<p>I'm showing tooltips like this</p>

<pre><code>$(clickedElement).append('&lt;span id="activeHelpTip" class="helpTip"&gt;Loading help...&lt;/span&gt;');
$('#activeHelpTip').remove();
</code></pre>

<p>A colleague suggested that on page load I append ALL possible tooltips with visibility none, and show/hide them on demand.</p>

<p>What's the difference?  Who cares?</p>

<p>Edit: Is it relevant that tooltips are provided by an ajax service?</p>
