Not sure if this makes them more like Twitter or more like a crowdsourced AP... But the New York Times has taken the realtime plunge with the launch of Times Wire, a twittery service that they describes as "a continuously updated stream of the latest stories and blog posts."
The news scroll updates every minute... Will they be "streamworthy"? I'm not sure. The challenge is that the feed is buried in the NYTimes site...
Note: You can get this and other posts as soon as I, well, post, from over at thedailylark.
