It's been almost 2 years, and nobody has learned anything? Let me be the first to start.
Last week, W3bbo helped me solve a problem relating to Storing Markup in Data-fields. He introduced me to Markdown, a great way to keep your content clean, and convert it to HTML upon displaying.
Now my database is getting cleaner and cleaner, and I even have my wife working on converting the rest of it, as a testimony to how easy it is to format your data with markdown - even my non-coding wife can do it.
