With the emergence of Web 2.0, there has been a dramatic surge in user-generated content. Although the Internet provides greater freedom in self-presentation, computer-mediated communication is characterized by a more relaxed attitude to grammar, spelling, and punctuation. The language of the Internet, or textspeak, may be suitable for casual interactions but inappropriate in professional contexts. Participant perceptions of an author's personality were tested in two distinct contexts (formal vs. informal) and the written information was manipulated under three levels of textspeak: none, low, and high. Participants judged the author as less conscientious and less open but more emotionally stable when textspeak was used. However, context had no impact. Personality perceptions of textspeak users differ to those who write in Standard English, and this is likely to extend to informal impression management contexts (e.g., online dating). These findings also have a number of implications, for example in terms of screening applicants via social media.
