Hi, I recently launched a Facebook Application, and I'm really surprised it is not as viral as I thought. The application is really nice looking and not full of ads, it publishes to open graph, prompts for publishing to the wall and offers incentive for inviting friends. Can you still build a clean (not spammy) viral Facebook App ? How do you drive trafic to it, and make users share the app to their friends ? The best way I found for now is posting to groups with fake profiles, but I can only get few users with that technique... Thank you for you answers !
