I didn't mean that to be demeaning at all. I seriously urge you to implement that vision even as a bootstrapped side project to your main gig. If you want to "build something (you're) proud to sign (your) name on", chances are whatever you build will display that authenticity, which will either resonate with customers or not. People love authenticity, perhaps customers not so much. The market can be brutal and just because something is "better" or more genuine does not necessarily equate to revenue. You have already started a big part of your story, explaining why your vision is "better". Go ahead and implement something incorporating that vision, explaining its advantages to the market. At the end of the day, you will at the very least feel true to your self. A job may not give you that.
