Great analysis! When you mention “Don’t just model invites, model multiple viral channels” are you suggesting that you break out each cohort into more granular segments, such as “new user from email invite, new user from twitter link, new user from blog widget, etc” then drill into each segment to view the performance? Have you seen disparate performance based on the 'type' of invite a user received from the viral loop?

Nice post, It’s incredible to see how quickly this is all happening.
Because Facebook is all about friends, I think the apps that deliver true value to friendship networks (like the carpool and couchswap apps) are the ones to watch.

[...] Hitting saturation in viral networks Another important limitation is that there’s a finite number of users out there, and after you churn through all of them, all you have to look forward to is the long plateau.

Hi Andrew!

I played a bit with your excel-sheet and your equation and explored that your results in excel doesn't match with your posted equations. You never used something like ^t.
In excel you use something like
u(t)=u(t-1)*((1-u(t-1)/carring_capacity)*conv*i)+u(t-1)

Where is the mistake?

Definitely agree with you Andrew, retention is really important when developing a new Facebook app, or any app for that matter. Great math, great stats, and great post.

Hi Andrew,

I did a talk a while back on your findings to the Facebook Developer Garage in London, which I help organise. After posting about my talk ended having an discussion with a reader over some inputs which create a saw-tooth in the results, you might find the conversation interesting - http://www.joshuamarch.co.uk/2008/04/jumping-shark.html

Cheers,
