Is there one link, story, picture or thought that you saw online this week that you think somebody you know must see?

My friends: Alistair Croll (BitCurrent, Year One Labs, GigaOM, Human 2.0, the author of Complete Web Monitoring and Managing Bandwidth: Deploying QOS in Enterprise Networks), Hugh McGuire (The Book Oven, LibriVox, iambik, Media Hacks) and I decided that every week or so the three of us are going to share one link for each other (for a total of six links) that each individual feels the other person "must see".

Check out these six links that we’re recommending to one another:

1. Dancing Plague of 1518 – Wikipedia. "Definitely the weirdest thing I’ve seen this week, and I’m sharing it for no other reason. What it says about how I spend my time is another matter entirely. Did you know that there was a plague of fatal dancing in Strasbourg in the 1500s? While this wasn’t a medieval rave, it does seem to be a case of mass hysteria. Makes modern political decisions pale by comparison." (Alistair for Hugh).
2. College Students Are Less Empathic Than Generations Past – Scientific American. "As we get older, we all start to believe we’re part of a kinder, gentler, vanishing generation. And when the news shows us twelve-year-olds attacking commuters, while their friends look on and strangers record it on cameras, it’s easy to believe. But are we really? Turns out, yes. This piece from Scientific American looks at research into how we empathize with others." (Alistair for Mitch).
3. Universe captured in mind-boggling detail by Sloan Digital Sky Survey – The Guardian. "There’s a new trillion-pixel image of the universe. I guess the earth is a pixel. Kinda puts your problems in context, doesn’t it?" (Hugh for Alistair).
4. Flood – City Of Sound. "This past week there were massive floods in Queensland, Australia. Dan Hill, of the fabulous blog City of Sound published this moving and intense reportage. This is why blogs still matter, and always will." (Hugh for Mitch).
5. The science of the hashtag – Twitter Media. "The other week a meme exploded on Twitter around the hashtag #LessAmbitiousMovies (for the record, I thought my contribution of A Clockwork Beige was pristine). It begs the question: what makes a hashtag go viral?… and what do the analytics looks like?" (Mitch for Alistair).
6. Celebs, They’re Geeks Like Us: Libraries of the Rich and Famous – flavorwire. "This is an iteration on the infamous MTV show, Cribs, that I think both Hugh and I could definitely wrap our heads around. Who wouldn’t want to see what the home libraries of the rich and famous look like? How do they chill with a fine book and what does the space look like? Karl Lagerfeld‘s book space really blew my mind." (Mitch for Hugh).

Now it’s your turn: in the comment section below pick one thing that you saw this week that inspired you and share it.
