I thought a lot on this application.

Can you please guide me on

1)Is this idea worth trying and to focus on? Iam relying on

    a) friendfeed API to fetch diverse content like delicious, facebook,Google Reader 
    b) twitter API for twitter

2) Its sole aim is to provide interesting content for a topic (users can rely on this if he needs to keep track on a topic ),

3)What parts of the application requires an improvement?

Thanks
