Knowledge in the Internet Age - networked knowledge - is becoming more like what knowledge has been in the past few hundreds years for scientists: it's provisional; it's a hypothesis that is waiting to be disproved.

I mean, I've been stupid in the past, and I've learned from that.

Municipal debt outstanding doubled in the past 10 years. And in the past 30 years, the U.S. has been in real economic nirvana.

I used to like humorous people in the past, but these days, I like serious people more.
