.md is the markdown file extension, so having a .md TLD is a clever and amusing idea imo as Obsidian is, after all, a markdown editor.

It's clever until you hit issues with uptime, or breaking the specific rules of the TLD. I'm also a supporter of Obsidian, but it scares me that the domain is under the whim of the Moldovian government and could get shut down/redirected if someone who uses Obsidian Publish decides to write "bad" stuff about government officials since the TLD doesn't allow that.

> could get shut down/redirected

The latter is my concern. Until 2020, Moldova had a pro-Russian government. They could easily return to power. I would see Moscow having zero qualms about requesting e.g. certain visitors be re-directed to a Kremlin-controlled server.

md = markdown

> md = markdown

Makes sense. Is (EDIT: the use of the TLD) .md a convention in the markdown community?

Yes. I have seen the .mdown extension also, but .md is the default in every editor I've used, and it's a default for readme files on Gitlab and GitHub.

We're talking about the website here, not the file format. .md is the top-level-domain for Moldova, Obsidian.md exists at that address by the good graces of the Moldovan government.
