Despite evidence that anger is routinely expressed over the Internet via weblogs, social networking Web sites, and other venues, no published research has explored the way in which anger is experienced and expressed online. Consequently, we know very little about how anger is experienced in such settings. Two studies were conducted to explore how people experience and express their anger on a particular type of Web site, known as a rant-site. Study 1 surveyed rant-site visitors to better understand the perceived value of the Web sites and found that while they become relaxed immediately after posting, they also experience more anger than most and express their anger in maladaptive ways. Study 2 explored the emotional impact of reading and writing rants and found that for most participants, reading and writing rants were associated with negative shifts in mood.
