Part 2 of what looks to be a 3 part series on the “twitter language.”
AFAIK–As far as I know I have seen this used in instant messaging as well.
CC —CC’s carbon copy. Used the same way as email or a paper document except that it is followed by the twitter handle of the cc user. For Example CC @DavidFlom
CX–Correction When a tweet is sent out immediately after with some kind of correction…in my case it seems to be spelling error that need to be corrected most often.
DM Direct message. A way to privately message someone who is following you on Twitter. It is the only way to have non public (private) conversation. For example “DM me for more info.” I would not send any personal information in a DM…follow the same rules as you would for email,more information is here.
FF–#FF stands for “Follow Friday,” It is followed by a list of Twitter users using the @ and is an endorsement by you for your twitter followers to follow the accounts listed in the tweet. I have not participated in this Friday tradition I prefer keep the people I am following fairly small, more information is here.
HT–The old hat tip a way to give a shout out to the person who originally shared content that you are tweeting, and is typically followed by the twitter account. For example HT @davidflom for the #cbj information.
ICYMI–In case you missed it I have seen this used in instant messaging as well.
MM– Music Monday This has pretty much died off, twtter accounts would post MM followed by the music they were listening to at that time.
MT or MRT Modified tweet or modified retweet. It is used to show that you’ve edited the original tweet, usually due to space restrictions.
More to come in the next post on twitter, let me know if I have missed any symbols or abbreviations.
