In 2012 I made up a bunch of WebIDs for my Facebook friends and sent them out all set up.  Really, all you had to do was load the cert in your browser for identity and set up your RDF.  I watched @d14fc624  (RIP, Henry) presentation over and over again, trying to understand.  I knew people would be unlikely to create their own cert.  It was a good idea, though, completely decentralized.  TBL is still at it with Solid and Inrupt.  This may be the best we can do, here, though.  Works for me.  TY
