Online chat rooms allow people from all over the world to exchange opinions on various topics of interest. A side effect of such conversations is "flaming," which is negative criticism of others' contributions to the conversation. A paper investigated the effect that personal criticism has on an individual. Data from a survey of 193 chat room users from this study are summarized here.
