I just recently switched my Web ID card (i.e. my primary web profile) website, over from Microdata to JSON-LD to get better, more fine-grained control over the structured data appearance, on Google Structured Data Testing Tool, and subsequently on Google Search.
Now I wonder, does JSON-LD structured data also work with Google+ (Google Plus) shared website link snippets, or will I have to switch back to Microdata to produce a rich snippet when sharing my site on on Google+?
