Nebulos

I posted my Nebulos code to the google Visualisation Gallery. I attempted to make it a Facebook App but it never took off. You can find the App @ Graphit. The App actually uses another Visualisation component, namely the famous 3D world cloud from Roy Tanck, the one that's on WordPress.
I am wondering if making some code open source, therefore "giving it" away has any potential to increase your application use & web page traffic.
