The definition of news

Usenet news can generally be thought of as public e-mail as that is generally the way it behaves. In reality, it is implemented by different software and is often accessed by different programs. Different newsgroups adhere to different topics, and some are "moderated", meaning that humans will try to manually remove off-topic posts, especially spam. Most established newsgroups have a FAQ, and people are strongly encouraged to read the FAQ prior to posting.
