I know this is old but I just started to embrace Markdown and found myself asking this same question. I have a markdown document where I write notes on development, mainly C# stuff but also JavaScript and other topics. I think I came up with a pretty good solution; Simply add empty links prefixed with # to the post's title like so:

### My post title [#mytag]()

This allows me to add as many tags as I want, which is useful when a post contains more than one topic. Needless to say, you could add tags within the post itself. Perhaps most importantly to some of us, it renders nicely!. Ideally they would be invisible but there is also an advantage to displaying them.

Hope this helps someone.
