Tweet and ReTweet were in a boat. Tweet fell out, who was left? Wait, that's doesn't work,
Twitter RT means ReTweet
RT is an abbreviation for ReTweet, which is like Repeat. It’s like forwarding, but for Twitters instead of emails. If you see something really cool from one of the people you follow, you may want to ReTweet it so that the people following YOU (and not the original person) can see it. In the example above, amateria is repeating something from kfoxaz about a new music service.
This is only useful if you have followers that the original person doesn’t have – meaning, if you’ve only got a couple of followers, you probably shouldn’t bother with ReTweets.
I'm in if you do it.
