The points here are especially true on the web. Except maybe for the thing about sources — not enough people source their information, so we end up with an internet full of stuff we don’t know is true or trustworthy or where it came from. But most of the interesting stuff worth reading comes from real people, is opinion or experience-based, and doesn’t need to be so damn academic.
Break stuff up into short bits, write from the heart, and get to the point. Me likey.
