It depends on you. If you want to use this service, go ahead.
I built markdown2medium because I didn't like the other
service(markdowntomedium[dot]com). It worked fine, but the service generated a gist for each
code block. markdown2medium generates a single gist(per markdown file) and stores all the related files
Here's a medium post for reference and the associated github gist.
Markdown → Medium
Replace your markdown code blocks with medium compatible gists.
