Ask HN: Often HN changes original submission title–capitulate or change it back?

I've noticed that more and more frequently HN will alter the title of a submission.

Here is an original Popular Mechanics title:

>Will NASA's Next Super Telescope Finally Find Alien Life?

What HN just posted when I submitted that:

>Will NASA's Next Super Telescope Find Alien Life?

Usually any paper or study or article that uses the phrase "World's First" is automatically edited by HN to "First"— "World's" seems to be anathema.
