Microblogging systems, such as Twitter, are often used by marketers to send teasers or short messages that withhold key information. This is done in order to grab the attention and interest of current and prospective customers, and entice them to click through to learn more about the product or service being promoted. Platitudes are vague statements that lack real substance and are typically not effective marketing messages. Anagrams are word puzzles and are not typically used in marketing. Testimonials are statements from satisfied customers that can be used as marketing tools, but they do not involve withholding information.
