What is a MT on Twitter? MT means Modified Tweet.
When should you use MT? Anytime you retweet something with a change to the original tweet, it is appropriate to use MT instead of RT.
When you retweet someone, it is not uncommon to find you need to edit their tweet to stay within the character limits, especially if you want to add a comment. This is a perfect opportunity to use the MT. You can share the original tweet, and add your comment, while letting people know there is more to the quote. It does not take up any more space than a RT would, and everyone is happy.
Another time to use the MT is if you want to change or add a hashtag to share the tweet with another twitter community. This will ensure that people know you are adding the hashtag, and introducing this tweet into the conversation.
Used correctly, a MT is a great way to build upon thoughts and conversations that are happening on twitter. A MT is not a license to misquote people, or twist their words to give them another meaning.
