I have been building an RSS reader for developers called https://diff.blog https://diff.blog. It's havily integrated with GitHub. For example, when you sign up, it automatically follows the blog of developers and organizations you are part of. I have been working on it in my spare time during the last 2 years and it has been growing steadily. It has over 1200+ users now. Do give it a try!
