The top story among journalists last week was the economy, followed by the Iceland volcano.
The top story among bloggers last week was the Iceland volcano and the Polish plane crash.
The top story on Twitter last week? Google. Followed by Twitter.
So the Twitterverse basically spends most of its time talking either about Google or about itself. Twitter was also, strangely, concerned about something called an "immortal soul clause" in a game's terms and conditions. NASA, real actual news, comes in next on Twitter, followed by "online music." In other words, Twitter is a Twit.
