I like clean and well written code, but I don't have the experience or the knowledge (yet) to write code at his best; so, I was wondering if there's a site (like SO) where people can submit snippets, clases, implementations, etc., to be reviewed and posibly improved by other experiencied people, so everybody could learn from their modifications or advices.
I know stack overflow it's pretty much like this, but it is not designed for this purpose I think. Thanks.
