You've probably had the same annoying little problem as me then - having to copy/paste code from a Stack Exchange site to jsFiddle to answer a question. Stack Fiddle is something to combine the two into a wonderful milkshake of goodness!
Simple as that.
(This wiki will be filled with more beautiful things soon - honest!)
Please note: I'm new to using git and github, so if there's anything that I seem to be doing wrong (or could do better) then let me know! Thanks!
