Random thoughts from my day: One of the people I talked to at the interview used "criterion" correctly, which pleased me greatly.
Also, I was at the library, and wanted to see if I could use a computer, but didn't know the setup at that branch, so I was waiting in line at the reference desk. In front of me were an older middle-class looking woman, and a woman who seemed homeless (although who knows what either of their situations actually were -- we just made an unlikely-looking trio), and all three of us were asking about the computers. All three of us were being held up by the librarian trying to help a Chinese woman who was looking for a book on immigration and naturalization, but really barely spoke English. They pretty much worked it out. At least, I hope the Chinese woman got that what she wanted had to be ordered... I love the library!
