Ask HN: What do you do when you hit your MVP and are ready to show the public?

I've just completed a project that is ready for public consumption, but not yet ready for mass market consumption. I have just completed the minimum viable product portion of the service. I'm aware of some bugs and the site simply isn't built to scale or work in all localizations. So I don't feel ready for a big announcement with a rush of visitors. What are some methods for doing a small scale launch?
