It doesn't have a URL, as it is not publicly accessible.
To expand on this; directories in your user's home directory are not accessible via HTTP unless you have added a domain or sub-domain to the hosting system and specified that directory as the 'Web Directory' for the domain.
If you wish, you can add a free dreamhosters.com sub-domain to the hosting system and specify the 'whatdidifindouttoday' directory as the 'Web Directory' for this sub-domain. You will then be able to browse to this directory using http://yoursubdomain.dreamhosters.com
