If folks are interested in a Slack alternative for discussions around Clojure/San Francisco/Bay Area that does not have the 10,000 message history limit, I created https://clojurians.zulipchat.com/#narrow/stream/185452-clojure-sanfrancisco and I'll also invite the Zulip bot here to mirror any future conversations...
...that mirror will post to this topic in Zulip's slack-archive
stream: https://clojurians.zulipchat.com/#narrow/stream/180378-slack-archive/topic/clojure-sanfrancisco/near/158071820
