Backend in Python and front in javascript:
"talkatv is a comment service much like DISQUS or IntenseDebate.
talkatv is open source and free to use.
talkatv is embedded on any page and uses XMLHttpRequest level 2 and Cross-Origin Resource Sharing to post the comment back to the server.
talkatv requires JavaScript, but has a non-javascript fallback which is a link to the talkatv server with an optional but recommended ?uri={{ page_uri }} argument. If the uri argument is not provided, talkatv will try to get the page URI from the HTTP Referer header."
