See, this could be an interesting way to start a "how the sausage gets made" discussion. Readers tend to assume journalists or writers actually write their headlines. I venture a guess that the initial negative reaction to the blog post had a lot to do with "clueless" being in the headline. Readers tend to assume the person who wrote the post assumes authorship of the headline by virute of their byline appearing below it. Now, there have been valid critiques of the actual post in general, but I want to talk about headlines specifically.
In my case, having worked in print before, writers submit a suggested headline with their story when they file it. The person who actually writes the headline is the copy editor or copy desk, who are more concerned about how the headline will fit on a page and how much space they have to work with. They are also more concerned about grabbing a reader's attention with the headline. There are actual press association awards for best headline and page layouts. In a perfect world without space constraints measured in inches, writers would probably prefer that their lead became the headline, but those 20 to 25 words are going to be distilled down to about three to five once it gets to copy desk or completely changed and jazzed up. These guys are also usually getting pages to print at night, hours after you've filed your story and have left.
The thing that can sometimes happen here is that the copy desk can royally fuck up and write an incorrect headline. Since the general public assumes you wrote the headline, the person dealing with the fallout the next day is you. You can try to explain how headlines get written, but often you are the one that has to make the phone call to apologize to whoever the headline offended or wronged and end up writing the correction. The copy desk guys might get called into the editor's office, but they aren't the ones whose byline is on the story.
My question would be does Kotaku's editors write or approve headlines? Or is it something like Gawker has some unrelated team of headline writers tucked away in another office across town whose sole job is to crank out the most attention getting headlines all day for all their sites?
