From Steven Johnson.

A few months ago, I flew into London to give a talk at the Handheld Learning Conference, which had put me up at the Hoxton Hotel. I'd arrived late at night, and when I woke up, I realized that, for the first time in my life, I was waking up in London with no clear idea what neighborhood I was in. That seemed like precisely the kind of observation/query to share with the Twittersphere, and so I jotted down this tweet before heading out to find a coffee:

Waking up at the Hoxton Hotel in London — strangely unclear as to what neighborhood I'm actually in…

When I came back from coffee, I discovered, first, from a batch of Twitter replies that I was apparently in the neighborhood where half my London friends lived and worked. And then I noticed the envelope that had been placed on my desk. I opened it up, and it turned out to be a note from a producer who worked with Sir David Frost. They had noticed on Twitter that I was in London, and said they were very interested in having me talk with Sir David about Everything Bad Is Good For You for his show on English-language Al Jazeera.
