I learned a few years ago that HN also editorializes by dropping "world's" from titles

Before: Teens break record for world's longest kickball game

After: Teens break record for longest kickball game

I do actually agree with that change.

		It occasionally leads to kinda ambiguous headlines, e.g. "China opens world's longest undersea tunnel" vs "China opens longest undersea tunnel" It's a little unclear if it's the longest undersea tunnel in the world, or just in China

		It doesn't give enough recognition to the true longest game of space kickball.

... what a world.
