Every purchasing decision involves a trade-off between what I call fidelity and convenience. Fidelity is the total experience of something - how great the experience is. Convenience is how easy it is to get something. A live concert is a high fidelity way to experience music; an MP3 file is a high convenience way to experience music. Depending on the situation, one or the other is probably pretty appealing. What's not appealing is something that offers neither.

Our brains are great at knowing what to forget. We actually have to teach computers to do the same.

I'm that tech writer who gets on stage and plays funny tech songs. I wouldn't want that to be all I'm known for, but it's a bit of a differentiator.

In the long run magazines can't be a convenience play - the Web has stolen that. So magazines have to be high fidelity - a fantastic experience - to thrive. Magazines will survive the Internet age, but only the ones that give people an experience they just can't get anywhere else. A magazine will have to be truly loved to make it.

Some of what we're learning suggests a balance between exposing children to new things, yet giving them a chance to repeatedly experience something they enjoy, which builds "chunks" of information in their brains.

Chunking is the ability of the brain to learn from data you take in, without having to go back and access or think about all that data every time. As a kid learning how to ride a bike, for instance, you have to think about everything you're doing. You're brain is taking in all that data, and constantly putting it together, seeing patterns, and chunking them together at a higher level. So eventually, when you get on a bike, your brain doesn't have to think about how to ride a bike anymore. You've chunked bike riding.

Babies have not yet chunked anything. They aren't doing any high level thinking. All they're doing is sucking in all the data they experience in the world around them, and remembering it, raw. It's basically what extreme savants have happen in their brains.
