@hatter_the_mad You seen to be taking the view that because people value it at 100B that is is worth that. What happened to groupon?
Groupon is worth what its market price is today.
Can you explain to me how facebook is worth 100B because I have read plenty about it and none of it makes any sense to me.
I can't as I don't have the time to type it up.
However, consider how Facebook is a platform. It isn't an app or a tool, but a platform. That platform is becoming embedded in everything across the web: from logging into websites, commenting on blogs, even reading news articles or watching Netflix movies.
Facebook's advertising and targeting platform is incredibly immature (weak, in fact) and restricted to the Facebook website. Yet it already pulls in more than a billion dollars of revenue a year.
But also consider the direction that advertising is going in the coming decades and how prevalent it will be on our media (mobile, web, TV). Add to that the smart money in advertising wants to target users. Who, as well as Google who knows your browsing history, is best place to be a platform for targeted advertising and user information - not just on the Facebook website, but across other things (again, like Google Adsense)?
Which other network currently knows what news you read, films you watch, links you share, things you like, your life history (literally), travel plans, travel history, websites you login to, your family, growth of your family, websites you visit, what your opinions are, what you look like, brands you want to be associated with and what things that you share and recommend?
Not just that, but this particular network knows all that about your friends, too. It knows which of your friends influence your friendship groups the most, and which people are most likely to affect your consumption habits (media or otherwise).
Now ask yourself how much all this knowledge is worth to other companies who want to market to you.
Those are just some of the reasons why Facebook is currently worth $100bn, and if it keeps innovating in the platform and advertising space, why there is no reason it wont be hot on Apple's tail in market cap well within this decade.
