I understand your frustration, but many restaurant owners are not technically skilled, and having paid someone to create a web site, they may not know how to edit it. (If they went with an outfit that doesn't employ good software developers, it may not be easy to edit the web site without breaking it.) HappyCow listings are typically maintained by HappyCow users and not by the restaurant owners (who may not even know about HappyCow). I always call a restaurant before going to make sure they're open, and I update the HappyCow page if the hours have changed. You can help other vegans, and collect HappyCow points, by doing so.
