title: How to make WordPress "Add/Edit Post" form more Tumblr like?
body: <p>WordPress requires you give each blog post at least two fields: a title and text body content.</p>
  
  <p>I'm wondering how to modify WordPress admin so I can <em>sometimes</em> enter a single field for a blog post, in particular a URL, without WordPress requiring a title (related but not the point of this question: a custom theme would then know how to handle a post that only contained a URL, it would treat it like a "Link" post in Tumblr).  Ideally it'd be good if the "add/edit post" form could be modified so it only contains this single URL/Link field when this is wanted.</p>
  
  <p>I'm guessing this is possible through a plugin but I'm not certain.  I'm hoping some smart WordPress devs are here to share and brainstorm ideas for how this could be done.</p>
  
  <p>Thanks in advance for any help,</p>
