Reviving an old General Semantics proposal: borrowing from scientific notation and using subscripts like 'Gwern2020' for denoting sources (like citation, timing, or medium) might be a useful trick for clearer writing, compared to omitting such information or using standard cumbersome circumlocutions.
Moved to gwern.net
I'm quite excited about things like this. This specific proposal seems reasonable to me, I definitely prefer it over A!B syntax, which I've found confusing.
I previously pondered possible annotations to express uncertainty.
I'm quite curious when it will be possible to use ML systems to make automatic annotations. I could imagine some possible browser extensions that could really augment reading ability and clarity.
