Yahoo, like all home pages and web news sites are aggregators. Just like most websites these days. There are few original sources for international and national news reporting anymore. And the vast majority of websites simply buy the news they want.
It’s one big circle jerk with everyone citing pretty much the same sources all the time.
Variety - a silly taskbar program that changes my background randomly from my own selected sources with added random quotes. I have it set to change my background every 3 hours and the quotes every hour I think. I just can’ live without it anymore.
