This week two sites produced reviews of headphones. In the red corner (26 Aug), Marco Arment on Marco.org with "Portable, Closed Headphones Mega-Review" and in the blue corner (27 Aug), Lauren Dragan on Wirecutter with "The Best $300 Over-Ear Headphones". Considering the number of headphones included in each review and the time this would have taken, there cannot have been any copying or other nasty business. These apparently were researched and written coincidentally.

As with any piece that includes opinion, there are differences as to what was included and how the reviews should have been conducted. And this turned into a Twitter war earlier today between Marco Arment and Brian Lam who runs Wirecutter. Some may remember Lam as the one who upset Steve Jobs over a stolen iPhone a few years back. Perhaps as a result of that, he left Gizmodo and later left California.

The war of words (140 characters or less remember), was turning into a fairly fierce fight when Lam let slip one of those messages - concerning male anatomy - that will come back to haunt him, whatever the rights and wrongs of the disagreement.

Moral? Count to 5 and take a deep breath before sending anything.
