Well, the distinction between PKB (personal knowledge base) and "personal" publishing is kind of artificial. "Digital gardens" is a proof of that.
But it is a useful distinction, and Logseq/Obsidian seem indeed on course to become the WordPresses of PKB with their large plugin’s ecosystems.
However, you never know: It is a very fast moving (AI is barely in) and low entry (and exit, like @AthensResearch) domain. So, my personal wish is for better "interoperability" rather than any "lifetime licence" type of stability.
