ROBERT SCOBLE

Apple knows a lot of data. Facebook knows a lot of data. Amazon knows a lot of data. Microsoft used to, and still does with some people, but in the newer world, Microsoft knows less and less about me. Xbox still knows a lot about people who play games. But those are the big five, I guess.

There is a shirt company that is making sensors that go into your clothing. They will watch how you sit, run or ski and give data on that information.

If there's a danger at Facebook, it's the assumption that Facebook has us all locked in and we aren't going to go elsewhere.

Once you become known for one thing, it's easy to become known for a second thing, a third thing, and a fourth thing.

Apple, at its best, isn't a technology leader.

Oh, some day I'll tell you about why I wrote more than 1,500 Gmail filters. They throw away more than 300 emails every day. Every day. It's the best thing I ever did for my productivity.

I've seen this over and over again: people love it if you step up their experience. No one turns down an upgrade to business class in a plane.

My favorite conference so far has been Davos, the World Economic Forum. The people there were really incredible.

Link to your competitors and say nice things about them. Remember, you're part of an industry.

People thought I was an idiot, but I saw social networks were going to be more important, and it turned out to be true.

IOS users tend to be ones that really care about being online all the time. They also tend to be willing to pay for that. You might say they are richer users, which is partially true.

My favorite computer of all time? The Apple II that got me started, of course.

The problem is Twitter is designing the metaphorical equivalent of a Toyota Prius. A car for the masses. While I want a Formula One race car.

I was first in line for the iPhone, but I'm not a fanboy of any company - I'm in favor of anything that's best of breed.

I always tell people, start with what you're passionate about. If you truly are passionate, you'll keep it up.

Facebook is studying emotional reaction to things and bringing you fewer of things you don't engage with and more of what you do.

The people who can step up my experience are those who have a common set of experiences with people I know. Think about it. How often did a total stranger come into your life to make your evening better? Not very often. But the friend of your friend? That happens all the time.

Apple has hundreds of stores around the world that are beautiful, and they have a distribution system and a staff of 40 or 50 people that will help you.

The more Zuckerberg knows about you, the more media he will be able to bring you.

Highlight just hasn't proven to be very addictive to either me or my friends. We talk about it often. I keep running it.

With the advent of wearable technology, companies will soon be able to better provide ads to customers based on their real-time activity.

I'd try to become known as a world expert on 'something,' to take a small niche you can define.

This is what Steve Jobs understood: Brands are defined not by the best thing on the product but by the worst thing.

Post fast on good news or bad. Someone say something bad about your product? Link to it - before the second or third site does - and answer its claims as best you can.

Never change the URL of your blog. I've done it once, and I lost much of my readership. It took several months to build up the same reader patterns and trust.
