"Journalism’s Twitter style also should encourage not just the use of the RT for spreading original information, but also the MT (Modified Tweet) when a reporter retweets information in a post, but modifies it in some way, usually to shorten it to make room for a comment or addition.
Other abbreviations that should find a home in a Twitter style include HT (Hat Tip, or Heard Through) for acknowledging the source through which a reporter heard the information she or he is tweeting, and RR for a repeated tweet. Let’s not forget that while modern news operations work 24/7, individual readers don’t. Repeating tweets linking important posts can help expose them to fresh viewers who are just “tuning in.”
