"Paul Graham does not know shit about writing" is inappropriate. It is not something (I hope) you would say to someones face. We should not lose our civility just because we can be anonymous here.

>> Not one mention of Strunk and White: "Elements of Style" in a piece about writing?

Is it a reasonable expectation that every article about writing should mention "Elements of Style"? If one article doesn't mention it, is it reasonable to imply that the author "does not know shit about writing"?
