Tweet sheet

trendcentral.com has just published this handy cheat sheet for late-to-the-party Twitter virgins.

"For those still unfamiliar with the real-time microblogging service, here's a look at some of the Twitter trends and terms you need to know:

Celebrity Twitter Streams: While Twitter is primarily used as a self-promotional tool, a large part of the service's appeal is the voyeurism it offers. Through Twitter, celebrities are taking PR initiatives into their own hands, using their tweets to directly reach out to their fans who love following their favorite public figures with such intimacy. Of course there is always the chance you're following a fake, but the blog Valebrity verifies the genuine high-profile users.

Twitter Branding: Want to check out how the competition is using Twitter? A new directory of tweeting brands, Twitter Tracker, compiles real-time updates from companies using the service, such as Whole Foods, JetBlue, and Starbucks.

TweetUps: A TweetUp is an impromptu gathering of fellow Twitter users, many of whom have previously never met in person. These events are usually publicized in the feed of a Twitter user who has an exceptionally large number of followers.

Twitter Slang: Much of the Twitter lexicon originates in gaming terms, like pwned (which we wrote about in New Slang, w00t (it's like a cheer - woot woot! But those "o"s are zeros!), and FTW (for the win), all of which users often use to punctuate their tweets (e.g., "@twitterfriend I just dominated that run. W00t!").

Hashtags: A commonly used character of the 140 permitted in each tweet is the number sign, or the "hashtag." A hashtag is placed before a word in a tweet so that it can be tracked as a trend - Twitter trends change almost daily. For example, when candy company Skittles recently incorporated Twitter users into its online marketing, under the Trend dropdown menu on the Twitter homepage, #skittles was listed. Noted fantasy author Neil Gaiman has a large Twitter following, and after he tweeted about his 33,333rd fan ushering in the "Armageddon," within hours, #Armageddon was one of the highest ranking trends. The power of Twitter!"

Now you've now excuse. Tweet or face defeat!
