I don't use a public Github because my interesting code often isn't something I want to share with the public, particularly if it happens to include AWS credentials, API keys to various services, etc. All my most interesting sites have been money making endeavors as well, so I don't see any reason to give away the source code, or share it with the public. I do share the URL of the finished product, though, and that has been enough to land me quite a number of job offers, including the one that led to the startup position I am filling right now. I've never made a traditional resume, and I've never made my code publicly accessible on Github but I've gotten along fine.
