Thereby, a feeling similar to a spoken conversation is created, which distinguishes chatting from other text-based online communication forms such as Internet forums and email.
Online chat may address point-to-point communications as well as multicast communications from one sender to many receivers and voice and video chat, or may be a feature of a web conferencing service.
With chatrooms replacing many face-to-face conversations, it is necessary to be able to have quick conversation as if the person were present, so many people learn to type as quickly as they would normally speak.
Some critics are wary that this casual form of speech is being used so much that it will slowly take over common grammar; however, such a change has yet to be seen.
Internet chat rooms and rapid real-time teleconferencing allow users to interact with whoever happens to coexist in cyberspace.
