Does The World Need Another Sex Columnist?

The story above is a college sex columnist's narrative about having sex all around the campus of the University of California, Berkeley. It raised a bit of a fuss (read the comments below the story) as sex columns often do. Talking about sex, it seems, is always rather controversial.

But let's make this about more than this particular story. Is there a need for sex columnists in general? Are we wasting our journalistic resources by over-covering this salacious subject (especially when Dan Savage has already answered every possible sex-related question)?

Do media outlets focus on sex because it will attract attention or because there is a legitimate service being provided to the audience?
