O.K., so instead of just criticizing, I thought I would help him with his piece, given I do this for a living and he does not, by rewriting his work. Here goes:

MARK WROTE: “Facebook turns 15 next month. When I started Facebook, I wasn’t trying to build a global company. I realized you could find almost anything on the internet — music, books, information — except the thing that matters most: people. So I built a service people could use to connect and learn about each other. Over the years, billions have found this useful, and we’ve built more services that people around the world love and use every day. Recently I’ve heard many questions about our business model, so I want to explain the principles of how we operate.”

KARA TRANSLATES: We old now. We big now. It came from my one really good idea: AOL sucked and I could do better and I did. Now the noise has reached me up on Billionaire Mountain, so I am going to have to pretend that I care.

MARK: “I believe everyone should have a voice and be able to connect. If we’re committed to serving everyone, then we need a service that is affordable to everyone. The best way to do that is to offer services for free, which ads enable us to do.”

KARA: No rich person is going to pay too much for this muffler, um, social media service, and poor people aren’t going to pay us at all because they apparently don’t have money. So everyone will have to endure the ads that we shovel out and stop griping, because free ain’t free, people.

MARK: “People consistently tell us that if they’re going to see ads, they want them to be relevant. That means we need to understand their interests. So based on what pages people like, what they click on, and other signals, we create categories — for example, people who like pages about gardening and live in Spain — and then charge advertisers to show ads to that category. Although advertising to specific groups existed well before the internet, online advertising allows much more precise targeting and therefore more - relevant ads.”
