Nice list! I like many of these "microfeatures" too. Some I have on my site (
https://evalapply.org), some I don't because I don't want to require Javascript for blog functionality. I think I have a few others not in that list.
This is my set of "microfeatures", which are all available in the post I linked below [1].
- All posts must have title, summary, dates (published, updated), one tag at least, and hot link to top of post (it's always #main)
- Open graph metadata for all pages (title + summary)
- All first-party content must be accessible as plain HTML
- Typography and separator elements to establish structure and distinguish functionally different areas of content
- In-page navigation (especially jump links to and from footnotes)
- Table of contents when needed, in a disclosure element
- Custom navigation to group a series of posts
- Markers for external links
- Captions for images and embeds
- Disclosure elements for extra context
- Footnotes (with links back to the referring text)
- Index pages with summaries (the main blog index, and each tag's index)
- RSS feed (global)
So far I'm reasonably happy with things as they are. At some point I'd like to participate in a webring.
