The text box to post a status on the profile page is unlabeled.
Screen-reader users should be able to navigate to the text box using the forms list dialog; instead of "Unlabeled1," the first element found in the forms list, it should say "post something"
Add a title attribute to the input element. Suggestion:
<input id="ida5" name="message" value="" class="statusField" type="text" title="Update your status message"/>
