I'm always mystified by the day-to-day workings of entities like Twitter that provide framework but not content, but I suppose it could be compared to the U.S. Postal Service, which manages to keep a lot of people employed doing lots of stuff other than writing letters.

Places like Hilton Head, with water adjacency and nice climates, are in high demand, and land values are insane. In the case of Hilton Head, which was developed in 1970 on what had been a mosquito- and alligator-infested swampy barrier island, land value has leaped from nearly zero to now unaffordable.

The lesson we have yet to learn from dogs, that could sustain us, is that having no apprehension of the past or future is not limiting but liberating.

I think the real reason is that life has no meaning. I mean, no obvious meaning. You wake up, you go to work, you do stuff. I think everybody's always looking for something a little unusual that can preoccupy them and help pass the time.

You could go crazy thinking of how unprivate our lives really are - the omnipresent security cameras, the tracking data on our very smart phones, the porous state of our Internet selves, the trail of electronic crumbs we leave every day.

I like the idea that people get engaged thinking about design, about creativity. I don't see how it could possibly be bad.
