This document provides guidance on how to effectively communicate within Twitter's 140-character limit by explaining several shorthand conventions:
1) Common abbreviations help maximize space, like "RT" to retweet and "@" to tag other users.
2) Hashtags (#) organize tweets by topic and make them searchable.
3) Emoticons (:)) add expression within few characters.
4) Links are often shortened to fit.
The techniques outlined help Twitter users communicate concisely while crediting sources and filtering discussions.
