Start small and grow it. I don't have the link handy, (someone else, please post it!) but I've seen it on HN before. There is a site that has the screenshots of a lot of famous sites before they were famous. They're shit. Heck, I can remember when Facebook didn't use HTTPS and you could rip passwords out of the air of your local college student union. Even if you don't intend for this to become famous, start somewhere! Just start working on it, and aim to release something that a non-tech user can use every 1 or 2 weeks. Don't do a time period longer than that, or you'll get stuck back in analysis paralysis.
