jsFiddle: A Playground for Developers
Saturday, September 24, 2011
I just ran across a pretty cool site. http://jsFiddle.net bills itself as a playground for developers.
It includes the ability to annote your markup. Just send someone the link, and they can see your code, the result, and your comments.
This site is already becoming quite popular on sites like stackoverflow.com as a tool to share markup snippets. But I think it's a great tool for just experimenting with.
