My levels of yak shaving:

1. Get on Mastodon.
2. Enable Activity Pub for my website using Bridgy Fed.
3. Embed h-card on my website's home page.
4. Add support for transclusion in Markdown files.
5. Modify Mustache templating code to add support for chasing dependencies using Shake build system.

Fortunately, the stack has unwound now, for I am posting this on Mastodon, and my website is Activity Pub enabled.
