I've been making https://AppGoblin.info for an overview of mobile app advertising ecosystem. I've been expanding it to include development tools and marketing companies as well.

My main, but longer, main project is building an MMP (mobile advertising attribution platform). It's really far from done, so if anyone is interested please reach out. I need help writing Android and iOS SDKs and with the analytic dashboard for the frontend.

Also, interested in starting a skyscraper construction blog if anyone is interested.
