Politely disagree. I read Colin's when it came out and it was as useful in 2009 as Filippo's is today. If you only pay attention to the cryptography community every few years when you need it for something, then usually a whole lot has happened in the interval. It is incredibly useful to get the perspective of someone paying attention to give you a breakdown of "where we're at today".
A great example is the other conversation about SHA-256. Colin's recommendation was "hey, better plan to migrate from this in the future." The thing that's happened between then and now is, well, SHA-256 is actually still 'ok' when used in current constructions. That's useful to know in 2026.
If I get busy building stuff, it'll be nice to have a check-in again in a few years (or earlier if something significant happens first).
