I've not tried it myself or seen an example, but given the structure, it would seem like Reveal.js might give you the the sort of functionality you're looking for while having many other affordances one might look for in a digital and/or online zettelkasten.

A fascinating combination of office furniture types in 1906!

The Adjustable Table Company of Grand Rapids, Michigan manufactured a combination table for both telephones and index cards. It was designed as an accessory to be stood next to one's desk to accommodate a telephone at the beginning of the telephone era and also served as storage for one's card index.

Given the broad business-based use of the card index at the time and the newness of the telephone, this piece of furniture likely was not designed as an early proto-rolodex, though it certainly could have been (and very well may have likely been) used as such in practice.

I totally want one of these as a side table for my couch/reading chair for both storing index cards and as a temporary writing surface while reading!

This could also be an early precursor to Twitter!

Folks have certainly mentioned other incarnations: - annotations in books (person to self), - postcards (person to person), - the telegraph (person to person and possibly to others by personal communication or newspaper distribution)

but this is the first version of short note user interface for both creation, storage, and distribution by means of electrical transmission (via telephone) with a bigger network (still person to person, but with potential for easy/cheap distribution to more than a single person)

One of the benefits of journaling on an index card is that the small space is much less intimidating than a large blank sheet, particularly when one isn't in the mood but feels like they ought to write. This is similar to the idea that many people find that microblogs (Twitter, Mastodon, Tumblr) are much easier to maintain than a long form blog.

He covers much of what I observe in the zettelkasten overreach article.

Missing is any discussion of exactly what problem he's trying to solve other than perhaps, I want to solve them all and have a personal log of everything I've ever done.

Perhaps worth reviewing again to pull out specifics, but I just don't have the bandwidth today.

History of Philosophy: Summarized & Visualized

This could be thought of as a form of digital, single-project zettelkasten dedicated to philosophy. It's got people, sources, and ideas which are cross linked in a Luhmann-sense (without numbering) though not in a topical index-sense. Interestingly it has not only a spatial interface and shows spatial relationships between people and ideas over time using a timeline, but it also indicates—using colored links—the ideas of disagreement/contrast/refutation and agreement/similarity/expansion.

What other (digital) tools of thought provide these sorts of visualization affordances?

I got stuck over the weekend, so I totally missed Kevin Marks' memex demo at IndieWebCamp's Create Day, but it is an interesting little UI experiment.

I'll always maintain that Vannevar Bush really harmed the first few generations of web development by not mentioning the word commonplace book in his conceptualization. Marks heals some of this wound by explicitly tying the idea of memex to that of the zettelkasten however. John Borthwick even mentions the idea of "networked commonplace books". [I suspect a little birdie may have nudged this perspective as catnip to grab my attention—a ruse which is highly effective.]

Some of Kevin's conceptualization reminds me a bit of Jerry Michalski's use of The Brain which provides a specific visual branching of ideas based on the links and their positions on the page: the main idea in the center, parent ideas above it, sibling ideas to the right/left and child ideas below it. I don't think it's got the idea of incoming or outgoing links, but having a visual location on the page for incoming links (my own site has incoming ones at the bottom as comments or responses) can be valuable.

I'm also reminded a bit of Kartik Prabhu's experiments with marginalia and webmention on his website which plays around with these ideas as well as their visual placement on the page in different methods.

MIT MediaLab's Fold site (details) was also an interesting sort of UI experiment in this space.

It also seems a bit reminiscent of Kevin Mark's experiments with hovercards in the past as well, which might be an interesting way to do the outgoing links part.

Next up, I'd love to see larger branching visualizations of these sorts of things across multiple sites... Who will show us those "associative trails"?

Another potential framing for what we're all really doing is building digital versions of Indigenous Australian's songlines across the web. Perhaps this may help realize Margo Neale and Lynne Kelly's dream for a "third archive"?

A user talks about why they've stopped using Roam Research.

I suspect that a lot of people have many of the same issues and to a great extent, it's a result of them not understanding the underlying use cases of the problems they're trying to solve.

This user is focusing on it solving the problem of where one is placing their data in hopes that it will fix all their problems, but without defining the reason why they're using the tool and what problems they hope for it to solve.

Note taking is a much broader idea space than many suppose.
