What's the best way to link to a namespace from an article? I suppose linking to cljdoc itself?
yes
May send a PR to add some adoc macros at some point to make it easier to write cross-output. Tbd :)
Note that CommonMark wikilinks only work from docstrings, if you are thinking of something similar for adoc. The benefit of using a full url in an article is that the link is navigable from GitHub to cljdoc.
I recently pondered about this topic too https://clojurians-log.clojureverse.org/cljdoc/2020-09-30
Adoc has native macros for explicit marking out an area, that wouldn't work on github either though.
