That's interesting. I was also taught glass is a liquid. We should correct people when they say it's a liquid OR a solid, because neither is correct; but I think we should not be so critical/furious if someone calls glass a supercooled liquid, etc. (ref: Tamman "frozen super-cooled liquid", the article: "a particular type of liquid"). Calling it an "amorphous solid" is obviously the currently accepted formal physicist category of course.
