Should I mention a magazine article written about my research in my CV?
I saw some researcher having "media coverage" or "general impact" columns in their CVs, see e.g. this example.

Other way to go (which I do) is to append to the respective publications "featured by [The Economist/Technology Review/2014 Highlights of [this journal]/John Smith's blog]".

IMHO as long you are not overdoing it, it should be a plus.
