Does anybody know of a privacy-respecting, decentralised address book project? I'm imagining a UX where I can have a profile containing a range of ways to contact me, and a range of ways to automatically and securely share that contact info, and an easily searchable address book for the contact info of the people who've shared it with me. I'm imagining an option for separate personal and professional profiles. Maybe this is a use case for #Solid?
