It's Twitter's combination of simplicity and complexity that is astonishing in the same way that minimalist sculpture was inspiring and enlightening.

For me, Twitter is a public persona. It's UbuWeb or Kenneth Goldsmith (as opposed to Kenny Goldsmith). I don't interact. It's a lousy form for conversation and opinion (what can you really say in 140 characters?), but a wonderful propaganda and sloganeering tool. I use it as a one-way street.

Most artists want first and foremost to be loved, secondly to make history, and money is a distant third or fourth.

Twitter is not art. But it inspires me in the way that art used to inspire me. Art used to make me see the world differently, think about things in a new way - it rarely does that for me anymore, but technology does that for me on a daily basis.

Automation and technology don't cure behavioral ruts: they just create new instances of them.

If you don't want something to exist - and there are many reasons to want to keep things private - keep it off the web. But if you put it in digital form, expect it to be bootlegged, remixed, manipulated, and endlessly commented upon.

I often don't endorse what I tweet, rather I want to throw things about to spark conversation or controversy. What I think about something is not particularly important when talking to thousands of unknown strangers.
