Use hashtags for categories.

[clemensv]

The "categories" in dasBlog (2003) predate (!) the concept of hashtags (2007).

I propose we throw the category editor out and pull hashtags from the submitted content plaintext. We can then also have an extra field for hashtags that shall not be visible in the text itself, but also fill that with hashtags.

What's nice about using hashtags in the text itself and for those to populate the categories is that you can take the literal text and cross-post it to, say, Mastodon with all the tags in the right places.

For display in the blog, we'd preprocess the tags for rendering and turn them into links into the categories view.
