As we have introduced people to Twitter, we’ve had a lot of questions about the Twitter lingo. Twitter is basically just like a very short blog, but there are some key differences, mainly the built-in social community. So we’ve got a two part post that will help explain common Twitter key terms.
This is PART TWO:
Retweet (RT): To help share cool ideas via Twitter and to give a shout-out to people you respect, you can repost their messages and give them credit. People call that retweeting (or RT), and it usually looks something like this:
“RT @Username: Original message, often with a link.”
Retweeting is common, and it’s a form of conversation on Twitter. It’s also a powerful way to spread messages and ideas across Twitter quickly. So when you do it, you’re engaging in a way people recognize and usually like—making it a good way to connect.
Trending Topics: On the right side of your screen and on the Twitter search page, you’ll see ten Trending Topics, which are the most-mentioned terms on Twitter at that moment. The topics update continually, reflecting the real-time nature of Twitter and true shifts in what people are paying attention to. A key feature of Twitter, Trending Topics aggregate many tweets at once and often break news ahead of the mainstream media. (Note that the trends often include hashtags, described below.)
Hashtag (#): Twitter messages don’t have a field where you can categorize them. So people have created the hashtag—which is just the # symbol followed by a term describing or naming the topic—that you add to a post as a way of saying, “This message is about the same thing as other messages from other people who include the same hashtag.” Then, when somebody searches for that hashtag, they’ll get all of the related messages.
For instance, let’s say you post, “Voted sixty times in tonight’s showdown. #AmericanIdol.” Your message would then be part of Twitter search results for “#AmericanIdol,” and if enough people use the same hashtag at once, the term will appear in Twitter’s Trending Topics.
Companies often use hashtags as part of a product launch, and conferences and events frequently have hashtags associated with them.
Tweetup: A tweetup is simply an in-person gathering organized via Twitter, often spontaneous. Companies use them for things like hosting launch parties, connecting with customers and introducing like-minded followers to each other.
Shortened URLs: With just 140 characters at your disposal, Twitter doesn’t give you much room to include URL links—some of which are longer than 140 characters themselves. If you post a link on Twitter via the website, sometimes Twitter automatically shortens the URL for you. There are also a number of services—URL shorteners—that take regular links and shrink them down to a manageable length for tweets, and some even let you track clicks.
