The question now is how to manage--if it is manageable at all--the information that comes to the forefront when anyone with a cellphone or a cheap laptop can blast information around the globe with a few keystrokes.

There are some reports that Indian authorities asked those in Mumbai to stop Twittering about the event in order to keep the activities of police quiet.

If true, that's a breakthrough. It's the sort of challenge journalists covering combat have long grappled with: What information should you share? Who decides what you can write? To what end?

In other words, we're all journalists now. Let's just hope none of us wind up being combat reporters, as so many in Mumbai did this week.
