This month, everyone’s favorite billionaire investor, NBA owner, TV star, and fitness fiend talks technology. 

If you were running Facebook, what would you do differently and why?

Mark S., Wilmington, DE

Financially, Facebook is crushing it, so I’d make sure I kept my employees happy. There’s not much I can add there.

Operationally, the one thing I’d change is to allow users to receive truly organic, algorithm-free feeds as an option. I just think in this day and age of living in an echo chamber, allowing information to flow organically is a good thing.

What’s the best book you’ve read lately and why?

Vince C., Lancaster, PA

The Master Algorithm: How the Quest for the Ultimate Learning Machine Will Remake the World, by Pedro Domingos. It’s a very readable guide to how all the different forms of artificial intelligence work and how they can impact each of us and our environment now and long term.

Are you a big supporter of certain kinds of work spaces? For example, are you a proponent of open-air offices—the kind with lots of cubicles and interaction, popularized in Silicon Valley—or do you prefer your employees to have private offices?

Cory E., Chicago, IL

I’m all for open spaces. I don’t have an office and don’t feel like I need one. I like the energy an open office brings and the ability for people to talk to each other more easily.

What’s the best habit you’ve picked up as a CEO? And what’s the worst you’ve ever successfully gotten rid of?

Winston L., Fresno, CA

The best habit is probably doing everything I possibly can via e-mail. The worst habit is not doing enough meetings because I do everything via e-mail. Fortunately, I hire people who are good at doing fewer—and shorter—meetings.

Everyone complains about millennials being bratty, disrespectful, reluctant employees. Have you found this to be the case?

Lance E., Pittsburgh, PA

No, because I don’t hire bratty or disrespectful people, regardless of age.

You manage to do so many things at once—running businesses, owning the Mavs, being on Shark Tank. What are your secrets to multitasking?

Ben S., New York, NY

No meetings, no phone calls unless someone writes me a check.

What are the apps you can’t live without?

Archie L., North Salem, NY

Cyber Dust, because I want privacy and as minimal a footprint as I can leave for my messages. Then NBA League Pass, because I’ve gotta watch the NBA, as well as Fox Sports GO so I can see my Mavs when I’m on the road. And MyFitnessPal: I track everything I eat and all my workouts. It’s the only way I can keep the weight off.

I read that you use Android instead of Apple. Is this still the case, and if so, why did you make that choice?

James T., Los Angeles, CA

I use both. Each is on a different network, so I always have service.

What’s the most exciting tech company out there we’ve never heard of?

Peter D., Boston, MA

If I told you, I’d have to shoot you.
