Say you have an awesome web app you developed in Django\Rails\PHP\Perl\Java\Bash\Awk. You one day wake up and decide you want to add support for push (real-time) notifications. Sure, you can run periodic AJAX calls, do long-polling, or utilize WebSockets yourself. But that's a lot of work, and that's what Socket.IO is for.

announce.js lets you seamlessly (well, almost) integrate your existing framework with the power of node and socket.io. just install it, add the proper client for your web framework of choice (currently, it's Django only), and send those realtime messages from your own code, in your own language, inside your own views.
