I recently launched a side project to try to leverage Facebook as a viral marketing platform to support a new social site called TruthTruthLie.me.
In a nutshell, people could create a "two truth and one lie" quiz about themselves and ask their Facebook friends to guess the lie. I created all the social hooks I thought I'd need (FB connect, FB comments, FB like, tweet this and all the big AddThis buttons), but regardless of how hard I pushed, I saw no virality at all.
I'd love you feedback as to why this experiment failed, my thoughts:
* requiring FB connect for login was too much to ask new users
* requiring login before creating a quiz was off-putting
* it was too hard to create quizzes (unlike ThreeWords.me, which was dead simple)
* it just wasn't that fun to do
* the concept was poorly executed
Thanks for you feedback, HN. Even though the site flopped, I'd love to get some shared learning out of it!
For reference, this is one of my own TTL quizzes: http://TruthTruthLie.me/mitch/Deadly-While-Driving/
Requiring users to connect with facebook is a fairly big ask and when you ask for it, you haven't really given users much in return.
