I need a viral, profitable facebook application.
The needed attributes are:
1. Viral. Easy to spread.
2. Profitable. Paypal subscription or rotating clickbank/paydotcom/amazon/etc. product links/data feeds.
Tell me what you can do or have done already.
Tell me also how your application benefits the facebook user and why would the user like to use it frequently and also share it with his/her friends.
If I like it I will buy it!
Thanks in advance and have a great day!
