I try not to answer a question if my answer will only be a duplicate of another, or there's a potentially good answer (in which case I would comment to suggest modification, or modify it myself). After all, we don't need many answers; we need a single, excellent one. Also I downvote duplicate answers.
Some of the source code of the answers (typically ones with lists) is manually wrapped at the width of the editor, so that the source reads good when their font is monospaced, as I set in my browser. I believe that Markdown is designed to look good when read as plain text.
