> would sooner have my team roll our own solution on top of Letta or Mastra before I trusted OpenClaw

A lot of teams explicitly did that for OpenClaw as well. Letta and Mastra are similar but didn't have the right kind of packaging (targeted at Engineers - not decisionmakers who are not coding on a daily basis).

> Participation in the Zeitgeist hasn't been regional in a decade

I strongly disagree - there is a lot of stuff happening in stealth or under NDA, and as such a large number of practitioners on HN cannot announce what they are doing. The only way to get a pulse of what is happening requires being in person constantly with other similar decisionmakers or founders.

A lot of this only happens through impromptu conversations in person, and requires you to constantly be in that group. This info eventually disperses, but often takes weeks to months in other hubs.
