It all depends on your project.
In my last job, we focus more on marketing sites. It seem relevant to stay with today's trends because everyone shares their landing page, checkout cart, or a generic dashboard. Anything that has cool visuals.
However, when my engagements got more complex sites, today's trends were no longer relevant to me. My problems were not "how can I make this page look sexy" but "how can I showcase a crap load of information that has no visuals on a page without making it look like shit and be intuitive.
So SvN is now on Wordpress? Interesting.
