> SPA => Nope This seems like a positive aspect for a blog? Most blogs are pretty far removed from being “applications”.
Would that be a negative aspect? Why wouldn't you try to bring the best possible experience to your reader?
A blog is (usually) a collection of documents. For this use-case, using standard hypertext (standard HTML documents delivered over standard HTTP to every standards-compliant browser) does bring the best possible experience to your readers.
Delivering a single HTML document stuffed with some hand-crafted Javascript code trying to re-invent hypertext will not bring a better experience to your readers (especially not any readers who disable JavaScript), unless your blog is something more specific/unusual than a collection of documents and actually fits something other than hypertext better.
