Hear me out:    1. jsfiddle has awesome gist integration.   2.
Embedding snippets from gist would allow me to not repeat
myself.   3. Publicly editable gists with easy browsing of
revision history makes collaborative answering painless.   4. By
including a link to the jsfiddle, anyone, on any platform, can
test the code with one click; no trying to reproduce locally or
guessing what is going wrong just by reading the code.  For
example, I have included a magic link to a jsfiddle in the
readme for this gist, check it out:   Wouldn't it be great to be
able to embed that nicely formatted code into my question or
answer? I understand that this is only really relavent to
HTML/JS/CSS questions, but I think it's really cool and it could
literally save MINUTES... I mean think about it! MINUTES!!!
Aren't you getting excited by how many minutes you could
save!?!?  I also think that more integration between Stack
Overflow and Gist would create all kinds of awesome in many
different scenarios. Am I taking crazy pills her
