I'm going to be in New York next week and would love to get together with anyone who is around on Tuesday night. Details TBD. Post a comment below if you can come. I know some people think that this is helping kids cheat, or get the answer without learning. I don't know... that doesn't feel right to me. I figure if you put a homework question on Quora and elicit a bunch of good answers that build on one another, you're probably going to learn more than you ... (more) Every once in a while, someone posts an obnoxious or adversarial comment on one of my answers. I generally delete these. Quora's philosophy is that you should have total control over your answer, including the comments underneath it. These kinds of comments annoy me, so I feel better when they are gone.
