Never heard of the platform, but it seems like a decent home for a mirror. Owning everything involved is definitely preferred, but there is still a place for sites like this. Shame that discovery is for paid users though.

Another reason to own your domain name and site and content. There’s dozens of good static site generators that support markdown.
