Right now we're focusing on patching bugs and providing a stable service, but in the future a premium service will be created which targets heavy users.
PS You can change the status of the last active host in your list (Minus.com) to shut down as well.
The primary reason it's still alive today is out of obligation to the URLs (2 million or so) that call it home. If you don't already find this fun and don't feel the same obligation, then you'll join the thousands of others littering the web with 404s.
