Haven[1] is my open-source, self-hosted side project for building exactly this (social networking based on self-hosted pages) in a privacy-first manner. There's a lot from the IndieWeb community that I want to emulate, and microformats is one of them--partly in order to create compatibility with the various MF2/IndieAuth client (phone) apps. My experience/opinion is that a circles-based approach is a usability nightmare since relationships are fluid and fuzzy, so Haven only has one "share group"--everyone with access to your Haven. That said, it's all built on open protocols (RSS), so it would be pretty straightforward for someone to fork it or build their own that implemented a circles-style approach to sharing.
