I binged his blog and content earlier in the year. Agree with you for sure, he's a very intelligent engineer. Noosphere looked interesting, but seems like it went from established seed funding to sunsetting within a year? I was perusing his GitHub for a while. Subtex(t?) was a particularly interesting feature of Noosphere to me. I tried writing a Subtex interpreter in Rust which kind of worked, as a hobby project. Needed to make it work better to actually use it. Curious if Nostr will reach to do something similar in time. Might also just try to send it myself one day. I think a lot of people trying to solve the "personal note-taking and list-making" platforms often end up in the knowledge graph bucket. I am thinking lots of users don't need knowledge graphs as much as they need an interoperable language such as Subtex, with a really great application, such as a slimmed-down LogSeq, to integrate with both their personal notes, and the personal notes of other Nostr users.
