Clojurians Log v2

FYI: the defaults for Zulip have been updated after some "community development" discussion, and topics have been made optional (you get a pseudo-topic of (no topic) 🙂 and new channels can be made web-public as opposed to just public (public = behind a Zulip membership wall, web-public is browsable without logging in). As reminder, this channel is mirrored to https://clojurians.zulipchat.com/#narrow/channel/180378-slack-archive/topic/clojure-bay-area and there is also a top-level https://clojurians.zulipchat.com/#narrow/channel/185452-clojure-bay-area channel over there! I can't remember why we decided to switch from #clojure-sanfrancisco to #clojure-bay-area here a few years ago -- maybe to be more inclusive? -- anyway, I renamed the Zulip channel to match (it was clojure-sanfrancisco previously).
