Previous Trivia Answer: Muhammad Ali.
Tired of finding the best website via user-submitted websites like Digg or Metafilter? Wanting more of a raw approach to finding sites that various people are visiting all around the world? Well, check out The Swarm:
http://www.swarmthe.com/go/swarm
This is a website where you can see what sites people are visiting at the time they are visiting them. An image of the site is provided so that you don’t have to click through to view the content unless you are really curious about a particular page. If you don’t like Flash, a text-only Swarm page is available.
Of course, there are a lot of lemons in there, as well as they occasional porn site, though Swarm browsers usually set those to be blocked pretty quickly. The more a site is visited, the closer it gets to the center of The Swarm and the more people see it. Go to The Swarm homepage to read more about it.
All of this works via a Firefox extension that anyone running Firefox as their web browser can load and use to contribute sites they browse automatically to the Swarm. (And you should be running Firefox for all web browsing if you use Windows, at the very least for your protection.) The more people that run the extension, the more sites they can find and rank, and the more interesting things we can find on the Web.
I’ve already found a site that I probably wouldn’t have found without it: Pjotro, the Man with the Musical Suit.
