(Main Application Page)
The main application when added will ask for a username and password and create a [url removed, login to view] account without them leaving the facebook. After they create their name it will take them to the application page which is the top 25 just as it is on [url removed, login to view] They will have the option to filter the deals by category, just like on [url removed, login to view], this will be through a dropdown menu on at the top of the page.
On the users profile page we could have the last 3-5 deals they voted "up" on...and maybe display deals the user shared(posted). Clicking on the deals would take them to the deal page on [url removed, login to view]
This could add the users voting,posting, and commenting activity.
A user should be able to share a deal with someone on facebook, each deal would read something like this..
