it would be helpful to escape the echo chamber of Silicon Valley and relocate to New York. Today New York has plenty of startup infrastructure in terms of funding and engineers, but it also has millions of creators and experts and consumers in fields beyond tech.
Dropbox and Github, which you mention as shining examples of ad-alternatives, are great companies that solve real, widespread problems and have real, sustainable business models. But I’m afraid “too many ads on Twitter” or “a slightly too restrictive developer API” are not actual, widely-held problems, and that Kickstarter-type donations aren’t a sustainable business model for a massively scaled social network.
