I disagree 
Blogish needs are different than trying to offer more SoMe-style for those who thinks Faceboom/insta/etc are the best possible UX/UI-experience.
So — out there could be a theme that looks a bit more like blog (what ever that now is meaning…). But this is just fine as it is now.
(WordPress is much more superior as blog-platform than Discourse; those are two totally different tools for different purposes…)
