WordPress can truncate Markdown
Here’s a heads-up for Markdown users.
Looking through my Categories and Archives views, I was startled to see raw, unconverted Markdown syntax in certain posts.
What happens in Categories and Archives views, is that posts are truncated to give readers an easy-to-scan excerpt. When this excerpt cuts Markdown syntax in two—-or cuts it off altogether—-the Markdown processor can’t convert the syntax fully.
The biggest victim is Markdown’s reference style links, which work like footnotes, putting the link information at the bottom of the post; these tend to get cut off. So until the WordPress crew fixes things (maybe with WP 1.5.1?), I’ve gone back to in-line linking.
