>I find it astonishing that what is basically a short message broadcast service can generate billions of dollars of revenue.
Basically a short message service? That's naive. Twitter is a marketing platform with 300m people signed up to receive marketing materials, people who also readily provide the platform with the details of what they like/would likely click on/spend money on, where they are in the world, what age they are, what gender they are and more. Of course it's extremely valuable.
The idea that social networks are useful for surveillance and the joke that the users are just useful idiots, massively predates the onion sketch as well though.
Twitter, like Facebook, has beacons on just about every website out there, thanks to website owners who are all too happy to make it easy for visitors to click "like" or "tweet" in the hopes of attracting attention. You don't even have to post a single Tweet for Twitter to know about what you're into.
