It's overly semantic.. but the core /document/ semantic outlining does seem useful to me, particularly when I started having to take accessibility into account when designing applications and pages. I will spend time considering if something other than a <div> is more appropriate for an element. I'm not going to spend very much time pondering the difference between <b> and <mark>.
