Wikiality:Factiness

It's good to sound like you know what you're talking about. 80% of being an expert is sounding like the things you're saying are probably true. But make sure that you don't get bogged down in details. You don't want to lose people by being too facty, because pretty soon things devolve into a fact fight, and suddenly you're no longer talking about how you feel about things, you're in an argument about "objectively true facts." Bleh. Make sure that you write from the gut, not from the head.
