This title used to read "How Optimizely (Almost) Got Me Fired", which is the actual title of the article.

It seems a mod (?) changed it to "Winning A/B results were not translating into improved user acquisition".

I've seen a descriptive title left by the submitter change back to the less descriptive original by a mod. But I'm curious why a mod would editorialize certain titles and change them away from their original, but undo the editorializing of others and change them to the less descriptive originals.
