I agree with the sentiment, but the correction here is unwarranted. He starts the post with "Here's what I've been doing". Assuming the poster is actually married to a woman, it's not incorrect to use "wife" here. His use of the second person in the list that follows ("your wife" and not "my wife") looks like a grammar mistake, not a sexist goof.
Hmm, a lot depends on how you read the context of the list. It's always best to give the most generous interpretation, so I retract that.
I'm amused/interested in how your comment changed the upvotes and downvotes my original had. Before it was positively received (+11 at the point I checked), but that was enough to drive it down to a +1 (no, there's no grave injustice here, no one should think to re-upvote it out of some misplaced sympathy). I can definitely see how your point would nullify it, but actively driving almost a dozen downvotes? HN folks are a fickle bunch =)
