RT is Twitter talk for re-tweet. It’s a quaint (Twitter is now 5 yrs old) courtesy where you share a link from another Twitter user. It does tend to recycle news. But I do think it has its relevance in advancing a story. Not all Twitter talk though needs to be re-tweeted. But it is an excellent way to form relationships online and give acknowledgment to something you find interesting and worth sharing. And isn’t that what Social Media is all about?
