Dropping Knowledge is a site where users can both pose and answer “deep” questions (Why do we lie to ourselves? Are women better human beings than men?)
It seems to be very heavily moderated for inappropriate content.
I could see it be a useful site for both ELL’s and my IB Theory of Knowledge students.
I’m adding it to The Best Places Where Students Can Write For An “Authentic Audience”.
Thanks to The Make Use of blog for the tip.
