We liked the idea of Parent Pages too. Unfortunately, it was underperforming and wasn't getting the page views on our corporate site to justify keeping the directory and continuing the program. We're not making wikis get rid of their parent pages, though, so if you think the great ones you've created are still useful to your community and audience, by all means please keep them!
