Can someone please explain this to me? Because I'm stumped.

I use Yahoo! for email (stop groaning). Whenever I check my email, there's a little landing page that shows me top Yahoo! news stories & some other stuff, including a box titled "Trending Now". I think this shows Yahoo! web searches that are currently popular. I often glance at them, but today my head snapped back because the Top Three were:

1. Adolf Hitler
2. Vlad the Impaler
3. Hope Solo

WTH? Genocidal dictator (modern), homicidal warlord (historical), & awesomely-named goalie (US women's soccer team). What brought any of them to mind today?
