Create a limited subset of markdown that's supported

[aron.carroll]

Allowing people to use the full range of markdown results in extremely messy output across the site. I'd suggest limiting support to only a subset of common use cases.

• Allow all inline elements, this allows bold, italic, code and links.
• Allow lists.

Disallow

• Horizontal Rules
• Headings
• Block quote and code (this may turn out to be useful and so could be included)

This way you get markdowns paragraph handling and a few inline styles without breaking the entire layout of the page.

Here's the full syntax if anyone is interested ​http://daringfireball.net/projects/markdown/syntax
