I was like, thirty chapters in before I remembered that you're supposed to indent paragraphs.
Or rather, because the tab key causes weird results when you type in a browser, I thought tabbing wasn't possible. It took my stupid self that long to realize there was a button that lets you indent on the top bar, and I was too lazy to go back and fix hundreds of paragraphs when not a single person cared...
Starting over fresh, I'd absolutely do it. If someone complained, I'd do it even more out of spite.
