Web-based Applications Keep Getting Better

I believe 2004 was a turning-point year for web-based applications, or weblications: I have the feeling that we’ve turned a corner, and that more “only obvious in hindsight” web-based application tricks will be developed in the years to come — thereby solidifying The Web As A Platform and continuing the spread of The Web Way […]

NYT Hightlights Decentralized Nature of Modern Filesharing

The Ninth Circuit had found Napster liable because the company itself maintained and controlled the servers that searched for the digital files its users wanted to download.

Can Brain Imaging Reveal the Seat of Strategy?

Below is a tantalizing paper combining fMRI imaging with an economics experiment. The headline’s a tease, of course, but it’s that kind of grand thinking that even gets little ideas rolling. The paper itself doesn’t sound too astounding, and certainly isn’t explanatory, but it was also only written up six months ago…! Social Science Working […]
