When journalists post to Twitter, their tweets collect on Muck Rack. The site seems confusing at first because it shows all the news from everywhere. But it’s easy enough to filter by subject area (or news beat), source (Fox, Forbes, or the BBC), or trending topics. Be sure to read the Muck Rack blog that explains the best web sources for the breaking news of the moment. The blog also lists the hashtags that Twitter users employ to follow the big stories, e.g. #Libya or #Japan.
