One of the things I use a lot with jsFiddle is the "Embed on your Page" option, which produces an iframe snippet like so:

Code:
<iframe width="100%" height="300" src="http://jsfiddle.net/existdissolve/ACGNt/embedded/" allowfullscreen="allowfullscreen" tabs="js,css,html" frameborder="0"></iframe>
This makes it really nice for including on blogs, and allows for customization of which tabs are included in the embedded result.
