What is RT (retweeting)?

I have quite recently joined Twitter and just gathering some knowledge about using it these days. Here is one of the basic term of it, explained for the beginners:

"RT" or "retweeting" is simply taking a twitter post from someone else and forwarding (rebroadcasting) it to your followers. Here are a few common ways to retweet a message (all do the same thing):

RT @originalsender: original message
retweet @originalsender: original message
retweeting @originalsender: original message

Retweeting can be a great way to add followers, as it pushes your @username into foreign social graphs, which in turn results in clicks back to your profile. You can also track your retweets using retweetist.
