What is a pastebin?

A  pastebin is a place visitors can post short text snippets, usually source code?, for review and revision by other visitors.

One of the most popular is  http://pastebin.com/, which is available for  download and private use.

Most pastebins are essentially public places, where anyone can view and revise the submitted code. Cocode takes many popular features of other pastebins, and adds user authentication?, access control?, and user comments?.
