Good to hear :) How are you planning on tracking where snippets are used? I personally liked an idea I saw once of 'tagging' snippets with their Gist URL in a comment above the code, but it was a fatally-crippled idea because no IDEs supported such things transparently.
As much of a hell as it will be to add / maintain, can I also request that they have version + library dependencies listed somewhere, somehow, so you automagically get the most-correct one? I realize I'm asking for a package management system, and I have yet to see one that isn't fugly, but I can dream, can't I? At the very least, I figure language-version is a necessity due to syntax changes.
