Some of my friends asked me to walk them through the virality of a social app so I put this little calculator together. With many building apps on a social graph such as facebook, I thought others may find this useful. It could help folks start to think about the metrics they may want to collect to tune their apps. Hope people find this useful.
The live version may only work in IE.
Clicking on the image should take you to the live calculator

pretty impressive, how does it work?
Not coming up.. is there an extension to the calc.
Try it in IE. Seems to work fine for me. Doesn’t come in Firefox for some reason.
RYK : It is backended with a simple model. No rocket science. But I think seeing things visually helps get the point home about where the effect of changes.
This type of visualiation can be done using crystal xcelsius software.Check this out.
