The H91: Using HTML form controls and links technique's Example 7b currently reads as the following:

<textarea id="ta_1" title="Type your speech here" >Four score and seven years ago</textarea>

I think it should read as the follows, because it's current value is "Four score and seven years ago" instead of the empty value that the preceding text is implying:

<textarea id="ta_1" title="Type your speech here" ></textarea>
