I like the support for markdown... I wonder if other web servers are thinking of supporting or already support that feature? Does it recognize GitHub Flavored Markdown (GFM)?
There exists a native Go package to render GFM, see second from the top at https://github.com/avelino/awesome-go#text-processing.
Someone has already opened an issue about it at https://github.com/shurcooL/go/issues/19, and I'm planning to take care of it.
Edit: Oh, I guess that was you.
