(for anyone who doesn't get it, Rich funded Clojure development via his retirement savings from 2005 until he ran out in 2009 https://dl.acm.org/doi/pdf/10.1145/3386321)
He did a community drive in 2009/2010 or so and a lot of us pitched in a little. Then he joined forces with Relevance to create Cognitect and that has funded his Clojure development since. Hopefully he gets a nice payday from this acquisition too.
