@Jobster123: I’m afraid I don’t understand what you mean.
The success of a directory does not depend on unique content but on whether you can entice users to register profiles. In addition, the success of the directory depends on how easy it is for visitors to search the directory and find the user profiles that fulfils their need. This means that a directory system needs to be easy to use for users who want to register but who aren’t computer literate or who don’t have time to figure out how to beautify their profiles beyond that which is necessary.
Of course, it would be great if Google could index the directory, but the strength of the directory lies not in the “description” field of each profile page, but in the way all the factual fields have been set up… because those are the things that visitors will search.
