For historical context, the Advogato site in question:

Apparently my account on the site is/was now more than a quarter of a century old... Gonna try to avoid thinking on that too deeply. :D
There's been a non-zero number of occasions since that time where I've observed situations that mirror the trust-based challenges Advogato sought to solve.
It is perhaps telling that as prescient as Raph's work on trust metrics was he later moved on to the notoriously challenging realm of font rendering--presumably because it seemed more tractable. :D
