This is an odd comment on "Hacker" news. There's a joy to be had in making things like this, even though there are better alternatives and it's often a weird thing to do in the first place. I often do not post the things I create here and elsewhere because I dread this kind of feedback. What do you hope OP takes away from your post?
Great question- rather then having to push a change to GitHub to see the format changes you can just mdvi it now. Iterate locally is nice
