The WaPo-owned slate.com has been doing frequent renaming of articles for a while now. I suspect they've been a testbed for Bandito or a similar system. One very frustrating side-effect is that I am often drawn to click on the same article multiple times. That's because it shows markedly different headlines for the same article, sometimes even on the same page simultaneously.
Case in point, as of right now, slate shows a headline: "What Bernie Sanders' Victory Means"
and lower on the page: "It's Official: Bernie Sanders Just Won New Hampshire"
both of which link to the same article, which sports the quotidian title "Bernie Sanders Wins New Hampshire".
The two front-page headlines are not just tweaked variants of each other, they sound like substantially different articles, one a reporting-the-news article and the other an analysis piece.
This is super-frustrating to me, because I keep feeling like the site is wasting my time and attention. It's starting to drive me away from slate overall. I wouldn't be surprised if something similar happens to the WaPo.
