It feels wrong to have everything within <blockquote>.

I would use <section>, or even <article>, for the outermost element and <blockquote> for the actual post content, itemprop="articleBody", in your example; the rest is metadata about the quote.

I'm also "Team Outside" for whether <cite> should be in or out of <blockquote>.

BTW, the <img> in the articleBody is missing `alt`.
