I scraped my favorite blogs and made a graph from the domains that each blog links to. You can see clusters forming of websites that talk about similar topics, like crypto, rationality, Canada, India, and even postgres! The visualization was made entirely in webgl with some neat optimizations to render that many lines and circles.
This is very cool but also not accurate, at least for jakeseliger.com. Henryn.ca lists 0 links from jakeseliger.com to nytimes.com, reason.com, and numerous others that simple search demonstrates are linked to, for example: https://jakeseliger.com/?s=nytimes.com&submit=Search I put up many links posts, so I probably link to an abnormally large number of sites.
The current visualization only shows the current state of the crawl, so it won't know about all of the posts.
