Ask HN: What should a Harry Potter fan build? ***

Some of you may have heard of Pottermore, which is a site for Harry Potter fans to explore the Harry Potter books, which was released last summer.

In response to the excitement and my interest in HP, I made a forum for Pottermore. It was popular for a while, but the forum has died because Pottermore still hasn't opened the next chapter of the Potter series. I have the forum : forums.pottermorehype.com and the Twitter: @pottermorefans with nearly 10,000 followers.

I really want to build something great that lets me entertain my interest in Harry Potter and Pottermore, and I'd like to Ditch the forums for this new idea.

One thought was to make a Harry Potter trivia site, because my followers enjoy when I host Twitter trivia contests. I'm having a hard time figuring this out. Any suggestions would be great!
