I've been thinking about developing a custom cms/site builder of sorts, pitch it to one restaurant and make both the customer and owner experience really smooth. On one side, I would have a restaurant directory with all the info, recommendations and what not, but the owner would get a site with no 3rd party branding and their own domain, charge a monthly fee and get free dinners on a bunch of places. But then I imagine explaining my idea to other people and having them ask "so, uhhm, like geocities?"
