NOTE: I have moved the information from this wiki into MyCreativeTeam's Twitter lists:
As a means to help PR people keep up with journalists and media outlets utilizing the social media microblogging application Twitter, My Creative Team has begun this wiki. The list initially was compiled at our blog, THINKing, from information provided by Red66, CNET, Poynter, as well as Twitter keyword searches on terms such as "journalist" and "reporter". Additionally, we found some Twitter accounts to be very helpful references, including @reportingon and @usnews. With this wiki now online, we look forward to having others contribute to the list. I've broken the list into sections, one for media people and one for media outlets. If you make additions, please keep them in alphabetical order.
Now, you can download the contents of the Twittering Journalist Wiki in Word format.
