There are attempts to explain what it is within the document, but I think it’s not easy to summarize or define. It’s a ~70MB html file that I’ve written in every day for about 10 years. I cover a significant variety of topics. It’s a journal, a wiki, and a social media replacement (I speak with others from the site itself), too. It serves many functions. If you end up makin’ your own site, lemme know. I’m an avid reader.
I am hypergraphic. From the estimates I’ve seen, there are fewer than a thousand humans (including the unknown) to have written as much structured, coherent text in their lifetimes.
I use Tiddlywiki as my base tool: https://tiddlywiki.com/
