Great question and a big one I am faced with at the moment. My thoughts for that is on each snippet, a user can provide a better way of doing this and this will either be showed back to the original user to decide if this way is better, or to have multiple options somehow. There is no official way to ensure code validity just as there isn't with StackOverflow. But we do have a voting system and invite only community so by having this, developers can upvote and downvote based on quality and this weeds out low quality snippets and invalid/bad code.
