Sure, but searching involves typing and will cause a huge drop-off in users. A better alternative might be a live real-time news feed, i.e. User A has just added Movie X to his recommendation list, User B has just created a movie list containing movies Y, Z, etc. The point is to give the impression of activity as well as immediate avenue for the user to start using your app.

Why would you sandbox your app in Facebook anyway? Is there any particular reason for putting it in an iframe on Facebook?

The "Roll" tab is in fact a news feed. However, since you are noy following anyone yet, there is no news to show. I need another way to make these updates though.

The app is basically a stand alone web app. And Iframe seemed to be the most painless way of integrating it with facebook. It was laziness and not any strategy which led me to decide on Iframe.
