Twitter allows groups and individuals to stay connected through the exchange of short status messages. Twitter encourages frequent updates, engagement and “retweeting” content. Account managers should tweet daily and be able to respond with some immediacy and engage in conversation.
You can’t control who follows you (unless you block them, which should only be done in the case of obvious spam accounts), but you can control who you follow.
Remember, unless you have explicitly protected your account (which is not recommended), all of your updates are public and findable.
HT: HT or H/T means “heard through.” If you are not retweeting something from Twitter, but would like to attribute the source where you saw the information, you can mention the handle after HT.
Via: If you learned of something via someone else or if an article you are tweeting is from a news source, you can attribute that by using via.
CC: Just like emails and memos, cc means “carbon copy.” If you want someone specifically to see your tweet, you can cc them.
