Wordpress blogs are not dead. 30% of websites are WordPress.

Are you sure it's not your reading habits that have changed? For example, I wake up and check my RSS reader (feedbin) where I subscribe to hundreds of individual blogs (many powered by WordPress). Actually this article was in my feed because I subscribe to HN RSS with a "Blog" keyword filter!

I don't have numbers but my anecdotal experience is that more blog articles I read are on WP blogs than not. Ghost is probably the other major platform I see along with static site generators.
