How can I get this theme?

He uses ld-json for structured data, which Q2A developers don't event care a word. Besides, the layout is cool, I really like the profile layout.

The blog feature is even integrated neatly.

Q2A already uses Schema.org structured data, what does ld-json add?

Json-ld ensures the creativity of theme developers because you won't have to stick to the positions of page elements.

I don't know if there is any hidden reason why Google prefers JSON-LD to other schema like Microdata, but maybe it's easier for them to preview pages by their search result quality raters.
