I am really enjoying the phenomenon of Facebook apps and totally loving the way they have exploded from zero to infinity and beyond so quickly! The arguement that facebook just added a quarter of a billion dollars of RnD to their platform is looking more and more realistic to me.
The apps I like the best are the ones that have exploded without the help of the directory and hardly surprisingly these have exploded because of interpersonal activity. The latest great app I wanted to show case is Free Gifts. The Facebook Gifts product is really cool and not too dissimilar to the ze frank concept of gimme some candy. The 2 mistakes I feel facebook made was making all gifts the same value (since surely if there were expensive and cheap gifts you'd give your girl/boyfriend a more expensive one) and not expiring the gifts after a given time (i.e. flowers might last a week, a teddy for a month etc...). Differentiation is key in many things.
Well the app above is giving away gifts for free and when you send a gift to someone they have to add the app to display it... how perfectly viral I really love it!
The image above shows the current user base and all without the use of the facebook directory, pretty incredible stuff, keep it up Zachary. I am excited to see how far this one goes!
