Tweets on twitter are composed of 140 characters or less. There's something refreshing about that. Just get out the info, the link and you're done. People appreciate the simpleness of it.
If you aren't familiar with tweeting or if you find there are some twitter things you don't get. Here is a break down of a tweet provided by Twitter.
A hashtag is any word beginning with the # sign. People use hashtags to organize conversations around a specific topic. Clicking on a hashtag takes you to search results for that term.
Sometimes you want to bring a Tweet to someone’s attention, but you still want all of your followers to see the message. So instead of a reply, use a mention. Include the @username of whomever you want to mention in your Tweet, and it will appear in the Mentions section (in the Connect tab). All @username mentions are clickable and link back to the mentioned individual’s profile.
You can respond to a Tweet by hitting the reply button. When you reply, your response is public, and will show up in your home timeline and the timeline of the person to whom you are responding.
You can pass along someone’s Tweet by retweeting it. Just hit the retweet button to send the original message to all of your followers.
Twitter’s link-shortening feature allows you to paste a link of any length into the Tweet box and it will automatically be shortened to 19 characters. This makes it easier to fit long URLs into the 140 character limit.
It's 22 pages long, but don't let that intimidate you. It is designed more like a presentation and not just a text heavy document. You can save it to your computer as a pdf and read it when you have time.
