In my post about engineering blogging culture, I didn't even touch on the most annoying aspect of the way the conversation has developed: people who won't believe harassment of women online differs from harassment of men online (in both quantity and quality). Luckily, Chris Clarke has got it covered in his post "How not to be an ashole: a guide for men." But I wouldn't restrict the audience like he does - he's got good advice for anyone who's tempted to dismiss others' experience. As a sometimes insensitive jerk, I can attest that Chris' advice doesn't only apply to men.
UPDATE: Let's also keep in mind that gender isn't the only axis on which these differences of experience turn.
