Nanomsg guy, Garrett D'amore, does a really good job rehabilitating the standing of the project and arguing for its utility and raison d'être. The existence of several ground-up implementations of the protocols (C, Rust, Go) is interesting, and the nng work (still in C, still wire-compatible, but rewritten at core) and WebSocket backend sounds interesting.

Apart from a few comparisons with ZeroMQ, governance wasn't discussed much. Nanomsg and nng are described as mainly a one-man show.
