It's 1:30 am EST and here are some archived links. The front page of /r/news and the front page of /r/worldnews don't mention the House passing the TPP fast-track. WTF, since when is this not news?
However, there is a post on /r/politics with over 5,000 upvotes but it's not on /r/all (at the time of this writing, it's 14 hours old and on the 3rd page of all). There are 9 hour old posts with fewer upvotes on all and the 12-hour old post about fake rhino horns is still hanging on, so while the time-decay algorithm is part of it, it's not all of it.
Yeah, the Americans are going to sleep, but this is international news. Also, remember that news and worldnews are both part of the default front page, but politics isn't.
Side note: I had to choose all images of "salad" in my captcha, and I was so scared of failing due to some poseur macaroni salad or something. But I passed. I'm not a robot, hooray!
