As a recently-minted PhD from a good university, there is at least some stigma associated with blogging or appealing to general population. your academic peers, determine where you get your next job, whether you get tenure, etc. You don't want them thinking that your research is frivolous because you have popular blog posts or press coverage. strong publications come first, everything else is lower on the scale. Another example is teaching. At top univs, getting an award for teaching as an untenured prof may indicate that you're not spending enough time on research.
