Every Facebook app I've used so far does 1-2 redirects when you first access it and lands you on a generic add application page with a bunch of checkboxes, expecting you to grant it access to all sorts of information without any hint of what the app is or why in the world you would want it- I find this incredibly annoying as a user.

I tried to make the user experience in my application as pleasant as possible. The app does not redirect you, instead it shows screenshots and explains what the app is and why you might be interested in using it.

There's a link to login that pops up a login dialog (again instead of redirecting to the login/add page) so that the transition from reading about the app to using the app requires a minimal number of clicks and page loads.

Also, URLs are very descriptive so when you send them to others they know exactly what is being linked, for example: http://apps.facebook.com/spreadarumor/about/Sumeet_Malakar-5...
