The Neiman Journalism Lab has a quick post on a site called Muck Rack, which aggregates tweets on journalists who tweet.
It started as "cesspool of banality", writes Zachary M. Seward, who now sees a certain amount of utlity to the site. Tweets are categorized into beats, loosely, allowing you to follow the trends that reporters are, well, following.
No matter that one of the top trends a couple weeks back happened to be Adam Lambert, the loser on "American Idol." bk
