Hi Cole
Yes, we use content page specifc URLs for any links we feel appropriate. Directories are not a highly thought of any more as a good SEO practice, as this became repositories for links links etc. This adds no real value to the user of potential user of a directory.
If the directory is something like Yel, we would want only parts of our site to link to their category heading where we are listed under. So we would not want our generic home page linking to a specific heading in Yel, as this is not useful to the end user, who would click the link and then have to start to search for what they really wanted.
Specific links at this level are liked by Google, because the link is 100% relevent to the user
Hope this helps
