Life's too short for anxious score-keeping

It is a work of psychogeography, albeit in a less explicit sense than Iain Sinclair's or Will Self's. It had to be fiction though, because I needed that freedom of including whatever belonged, and cutting out whatever didn't. The main fiction in it was matching Julius' generous and self-concealing character to New York's generous and self-concealing character. I think this also adds to my answer about New York's personality in the book.

In a sense, Open City is a kind of Wunderkammer, one of those little rooms assembled with bric-a-brac by Renaissance scholars. I don't mean it as a term of praise: these cabinets of curiousities contained specific sorts of objects - maps, skulls (as memento mori), works of art, stuffed animals, natural history samples, and books - and Open City actually contains many of the same sort of objects. So, I don't think it's as simple as literary inclusiveness.

What's interesting about Twitter is the unmediatedness of it, the directness of it. I'm on a train somewhere in New York and I send out a tweet. Somebody sitting at dinner in Bombay checks their phone and they see it.

Each time I caught sight of geese swooping in formation across the sky, I wondered how our life below might look from their perspective, and imagined that, were they ever to indulge in such speculation, the high-rises might seem to them like firs massed in a grove.

Note-taking is important to me: a week's worth of reading notes (or "thoughts I had in the shower" notes) is cumulatively more interesting than anything I might be able to come up with on a single given day.
