Well, look at that. The Associated Press has reached 1993 or so, and realized that they can (and probably should) link to other sites
when reporting on a story that those other sites reported first. Of course, they're still learning some of HTML's features, such as the idea that you can link to actual words in a story. Instead, they'll be putting the links (via Bitly) in parentheses right after they cite the source.
Pickups will now include a parenthetical bit.ly link to the original story, in addition to the credit. So in the fireworks story, you might see: “According to the Boston Globe report (http://bit.ly/pDHZ6h)...” The change will be most noticeable on state wires, where pickups are common.
And, of course, they're still working out the kinks. Apparently, some of the tests didn't show up as links, but instead showed the full HTML text for a link (i.e., <a href="...">). Oops. Still, we welcome the Associated Press to the world wide web. Look around, you might enjoy it. Just, please, skip over the blink tag phase.
