For those of you who haven't seen this before ... every year, folks at Beloit College put together a description of the incoming freshman class (in this case, the Class of 2011). It's a cultural description ... describing the world that they grew up in. And, in particular, the world they didn't grow up in ... that is, the world of their professors.
It's mainly a cautionary tale for faculty, to remember that, no matter how much we hang out with young adults, we didn't live in the same world. And so we need to think about the things that we teach and re-invent them for the modern era.
But mainly it just makes us all feel old. :(
