Catching Elephant is a theme by Andy Taylor
It is straightforward, if somewhat naive, to calculate an approximate value per user by dividing through the publicly estimated value of a social network by its number of user to get:
- Skype = $12.8 (purchased at $8.5bn, 663m users)
- Linked in = $53.7 (market cap $6.23bn / 116m users)
- Foursquare = $60 (rumoured summer round at $600m / 10m users)
- Facebook = $125 (upcoming IPO estimated at $100bn / 800m users)
- Zynga = $43.1 (upcoming IPO estimated at $10bn / 232m users) (in progress value changing regularly)
- Twitter = $18.4 (last round rumoured at $7bn / 380m users)
