What have you learned from A2K? I'm not talking about touchy-feely "I've learned to respect different peoples and cultures" type of thing. I'm talking about solid factual information that you didn't know before.
For instance, I've learned:
About French rhyme schemes,
grâce à Setanta;
Various new insights into German words and phrases from
Walter, hamburger,
und so weiter;
All about eighteenth- and nineteenth-century field artillery (very useful knowledge to have these days) in
this thread.
In addition, after getting involved in several drug legalization threads, I've had to learn far more about marijuana than I've ever wanted to. And, as a result of my run-ins with the non-dualists (
fresco, JLNobody and
twyvel) I've read some books that I never would have read otherwise.
So, what have you learned?
