Code snippets have been around for a very long time. One of the great features of
Allaire HomeSite was that it allowed you to save code snippets for later use. These days there are entire websites devoted to code snippets. Here are some of them:
- http://www.webmonkey.com/code-snippets/ Webmonkey, because it's an original.
- github.com "gists" https://github.com/search?q=gists
- http://snipplr.com/
- https://wordpress.org/plugins/code-snippets/ snippets for WordPress
Pastebin is not a snippet website, but deserves mention because it solves an equally important function for the programmer: it allows you to share code while you are working on it, without flooding your IRC or communication channel.
