They changed the link’s title, I guess...
You’re right. They changed the title. Probably since there had been another article with the same name (or close to it).
Now it’s — “Obama’s Epic Green Fail” and they’ve moved it from the blog section to the main articles section.
Thank you for noticing and tracking down the reason.
