This is fairly common practise - for example pastie/pastebin, Skitch, Facebook - all have 'private' URL options. I thought it was obvious, but that's only because I immediately understood the implications of a shareable URL. That's not going to be obvious to everyone, and GitHub really should change the "[lock icon] Create Private Gist" to something like "Create Hidden Gist". "Hidden" implies it's there if you find it. "Private" implies a whole lot more.
