Today has been a big day for Twitter. (OK, lately every day seems like a big day for Twitter.) Over at The Globe and Mail, columnist Ian Brown conducted a live Twitter conversation over lunch, dissecting the growing urge to tweet. (With characteristic erudition, Brown explains it has something to do with fear of death “ though narcissism seems to play a large role as well.) And just a few hours ago, Booker prize-winning author Ben Okri began tweeting the first lines of his Twitter poem, which read:

I sing a new freedom “
Freedom with discipline.

The Nigerian-born Okri, author of The Famished Road, will continue to publish the poem line-by-line via Twitter over the coming weeks, to mark the April release of his new book Tales of Freedom. The final poem will be available in its entirety on Okri’s MySpace page.
