This is one of the cases where I'm going to ask why I'm downvoted. The HN title says the opposite of what the WaPo title says. And not only is this not a problem, but I'm causing problems by pointing it out?
That said, they’re probably right that the title should be fixed. It’s just getting a bit... well. I just wish we would all be a little more grateful for how much effort a site like HN takes to run. It’s also not so easy to get good moderators with tasteful editing abilities; imagine what a disaster it would be if Reddit let a subset of mods control most titles on /r/all.
I suspect the title is broken in this case because the title gardeners are taking a well-deserved break, hopefully enjoying the evening with their families.
